Abstract
This paper argues in defence of the thesis that metaphysics is an indispensable discipline, the
negative views of the critics notwithstanding. Metaphysics, the paper opines, is the foundation and
most basic branch of philosophy. The paper strongly argues in favour of metaphysics and shows that
rejecting metaphysics radically is an impossible feat, which if it were possible will not only destroy
what binds and keeps society together but will also imply the absence of God and the idea of the
divine which culminates in the destruction of the foundation of religion and other human disciplines
and society itself. The cardinal discovery of this paper, therefore, is that metaphysics cannot be
radically rejected because it is the foundation of all systematic human inquires. Upholding
metaphysics, the paper argues, will help us understand that reality consists of much more than what
we perceive with the senses.

Philosophy, as a body of knowledge, is generally believed to be pure abstract speculation
about theories that have no bearing on practical life. Consequently, philosophy is generally
considered as irrelevant to practical life. The attack on philosophy has been more excruciating on
metaphysics as a branch of philosophy. With the polemical ventures or adventures of philosophers
like Hume and Kant as well as the positivists, we sharply grasp a total rejection of metaphysics. For
this class of thinkers metaphysics is not just not a necessity, it is in fact meaningless. Thus, it is
nonsensical to venture into or dedicate time to it. What matters and is of relevance is that which can
stand the tribunal of experience.
Although, it is a fact taken for granted that metaphysics does not serve a utilitarian purpose,
but that does not rule out its necessity, relevance, significance or value. Metaphysics is concerned
with being in general, hence its conclusions will apply to everything which falls under the extension
of the concept of being. This write up sets out to establish the necessity of metaphysics. To
adequately attempt this task, the reason why metaphysics cannot be radically rejected will be
underscored, followed by an exposition of the metaphysical foundations of other disciplines and a
consequent examination of the implications of the absence of metaphysics. Evaluation and conclusion
would end the work. But before then, it is pertinent to explicate what metaphysics is all about.
The Notion of Metaphysics
The word “Metaphysics” derives from two Greek words, “meta” which means “after” and
“physika” which means “physics” (or nature). Thus the word metaphysics, literally means “after
physics” and it was first used by Andronicus of Rhodes, the editor of Aristotle‟s works (Omoregbe,
2006,p.ix). Aristotle had some treatises on physical matters which bore the title, physics. He also had
some other treatises dealing with non-physical matters, but without a title. In his arrangement of
Aristotle‟s works while editing them for publication, Andronicus placed the treatises dealing with
non-physical matters, after those dealing with physical matters. He did not know what to call them; so
he simply called them “after physics” – “metaphysika”. That is, the treatises that come after those
dealing with physical matters which bore the title physics. This was the origin of the word,
metaphysics. Mautner (1996,p.351) captured the scenario thus: “When Andronicus of Rhodes, the
tenth Head of the Lyceum, edited Aristotle‟s works, the fourteen books dealing with the first

philosophy, were placed after the books on physics and were accordingly called metaphysics.”
Eventually “after physics” came to be understood as “beyond physics”, that is, beyond the
physical world, and metaphysics came to be understood as the discipline dealing with realities beyond
the physical world. This understanding of the word is not quite accurate because it is not only realities
that are beyond the physical world that metaphysics deals with. As a branch of philosophy, it is the
study of the totality of being, that is, the nature and structure of reality as a whole. According to Brain
Carr (1987,p.1) the ambition of metaphysicians is,
to reveal the true nature of reality, its contents and structure, to place
man within the cosmos in his relation to other kinds of things and to
his creator, to determine man‟s duty to himself and to God, and the
true route to happiness…..
Brown Thomas (1981,p.2) defines metaphysics as “the philosophical study whose object is to
determine the real nature of things- to determine the meaning, structure and principles of whatever is,
in so far as it is.” Aristotle called it “first philosophy” or again the science which studies “Being qua
Being”. Plato called it “Dialectics” and it is the core of his philosophy. For him, metaphysics is the
study of reality as distinct from appearances. Bradley (1987, p.2), an outstanding metaphysician of
our time, combines both the Aristotelian and Platonic concepts of metaphysics when he said:
We may agree, perhaps, to understand by metaphysics, an attempt to
know reality as against mere appearance, or the study of first
principles or ultimate truths, or again, the effort to comprehend the
universe not simply piecemeal or by fragments but somehow as a
whole.
On the whole, metaphysics as distinct from other disciplines, studies realities in their essences and
universality while other sciences study realities in their particularity.
Why Metaphysics Cannot Be Radically Rejected
Metaphysics as a discipline has met with excruciating criticisms by many. The wonderful
progress of the sciences during the last few centuries has been the occasion of prejudice against
metaphysics in a variety of ways. It is objected that metaphysics has no corresponding progress to
boast of. The comparison is unfair for many reasons. While the positive sciences have increased our

knowledge mainly in extent rather than in depth, it is metaphysics and only metaphysics that
can
increase this knowledge in its unity, comprehensiveness, and significance (Coffey, 1938,
p.25).
Metaphysics as a discipline has an enduring value to man. Thus Emile Meyerson, according to
Regis, Jolivet (1961, p.16) tells us that “Man practices metaphysics just as he breathes, without
thinking about it.” Man has often been defined as a metaphysical animal, which, apart from telling us
that man is a “reasoning animal” strongly indicates the characteristic power of reason namely, that of
looking beyond the empirical and relative to the absolute. “Man, therefore, from this stand point,”
says Regis (1961, p.13) “is of his very essence metaphysical;” which means that there is in him
something incapable of expression in terms simply of “nature” or “physics” something which always
radically transcends nature and which is to be described as spiritual. It follows then, that “if anything
is certain in the history of man as a thinking being it is this universal aim of his, under the conditions
of time and space, of the purely “given” and of entering that of the invisible and transcendent” (Regis,
1961, p.6). The overwhelming relevance of metaphysics makes it unreasonable to radically reject it.
Once we accept the distinction between appearance and reality, and realize that things are not always
the way they appear to us, then the role and value of metaphysics become evident. Once we accept
that man is not purely and exclusively material, that there are immaterial elements in his being then
we would be able to understand man‟s irresistible urge to go beyond the material realm of human life
and experience, and strive for the immaterial realm through metaphysics. “Even Kant who was
himself a devastating critic of metaphysics, still had to admit that the human being has a natural and
irresistible tendency towards metaphysics” (Omoregbe, 2006: 133).
Without Metaphysics, the fundamental ideas of science cannot be resolved into their ultimate
elements, nor can their validity be established. Celestine Bittle (1947: 7) underscores the above in an
interrogative fashion when he writes: “Do not the ideas of „cause‟ „effect‟ „quality‟ „truth‟ „relation‟
and similar ones previously noted, lie at the very root of all scientific knowledge? Science simply
presupposes the validity of these ideas. Consequently, to rob the above ideas of their objective value
is to rob science of the ground upon which it stands. And to accept these ideas without examination
and proof, means to leave the ultimate foundation of all knowledge open to question and doubt.

Man‟s mind can never be satisfied with this. If this ultimate foundation is insecure, every thing based
on it becomes insecure. It is the purpose of metaphysics to prove this foundation valid. Therefore,
metaphysics proves the rationality of science in general.
As a matter of fact, scientists themselves cannot avoid metaphysical problems, nor do they
actually leave them aside in their scientific discussions. Sooner or later, they must reach a stage in
their researches where metaphysical questions are asked. The deeper they delve into the mysteries of
nature, the more frequently they come face to face with metaphysical problems, which demand
definite solutions. Pursuant to this, Coffey (1938) has exposed the submissions of one who is a
sincere scientist as well as an earnest philosopher with regard to the necessity of metaphysics. As
Coffey (1938, p.27) points out:
The further science has pushed back the limits of the discernable
universe, the more insistently do we feel the demand within us for
some satisfactory explanation of the whole. The old, eternal problems
rise up before us and clamor loudly for some newer and better
solution. The solution offered by a bygone age was soothing at least,
if it was not final. In the present age, however, the problems reappear
with an acuteness that is almost painful: the deep secret of our own
human nature, the question of our origin and destiny, the
intermeddling of blind necessity and chance and pain in the strange
tangled drama of our existence, the foibles and oddities of the human
soul, and all the mystifying problems of social relations. Are not these
all so many enigmas which torment and trouble us wheresoever we
turn? And all seem to circle around the one essential question: Has
human nature a real meaning and value, or is it so utterly amiss that
truth and peace will never be its portion?
Consequently, the scientist cannot go very far without asking himself: what is quality, quantity,
causality, change and energy? What is the ultimate constitution of bodies, of protons, of electrons and
of matter? What is the essential difference between truth and error, substance and accident, power and
act? These are metaphysical questions, and scientists do actually discuss them. But they usually lack
the philosophical knowledge offered by a thorough understanding of metaphysics, and as a result they
often exhibit an ignorance of fundamental ideas and principles, which is harmful to the best interests
of science itself.
Metaphysics is a science of prime importance for every department of human knowledge.

Those who reject metaphysics are in error. For instance, the empiricists and the positivists see man as
a purely material being, forgetting that man is a multifaceted being. Man is not only material but also
spiritual. They also have a limited notion of truth. They see truth as only related to matters of fact and
experience. But there are metaphysical truths just as there are metaphysical experiences. There are
spiritual truths just as there are spiritual experiences. Kant‟s criticism of metaphysics is also faulty
because of his contradictory claim of knowing that the monumental world is unknowable, which
makes his claim false. The position of this paper is that metaphysics cannot be radically rejected,
because it is the foundation of all systematic human inquires.
The Value of Metaphysics
Henry J. Koren in his book: An Introduction to the Science of Metaphysics outlines the
importance of metaphysics. They include the following:
i. Metaphysics is a speculative science
Metaphysics is a speculative science and does not serve a utilitarian purpose. It is not studied
because it teaches us how to do certain things, but because man seeks to know “for the sake of
knowing”. As Aristotle (1932, 982b 11ff) points out:
It is owing to their wonder that men both now begin and at first
began to philosophize; … therefore, since they philosophized in
order to escape from ignorance, evidently they were pursuing
science in order to know and not for a utilitarian end. And this is
confirmed by the facts: for it was when almost all the necessities of
life and the things that make for comfort and recreation had been
secured, that such knowledge began to be sought. Evidently, then,
we do not seek it for the sake of any other advantage; but … we
pursue this as the only free science, for it alone exists for its own
sake (Metaphysics, Bk. 1, Chapter 2).
Although we may disagree with Aristotle on the necessities of life, it is clear that metaphysics does
American Journal of Social Issues & Humanities Vol.1 No.2. (Nov.2011)
©AJSIH Vol.1 No.2. (Nov.2011) 35-49 Ochulor, Apebende, Metuonu | 41
not serve any utilitarian purpose.
ii. Metaphysics has absolute value
As a pure science, the value of metaphysics can hardly be overrated. For metaphysics is
concerned with being in general; hence its conclusions will apply to everything which falls under the
extension of the concept of being. Consequently, whatever conclusions metaphysics reaches will have
absolute value; they apply to the objects considered in any branch of human knowledge and not only
in philosophy. For the objects of other sciences are things which fall under the intension of the
concept of being.
iii. Metaphysics renders secure the ultimate foundations of all sciences
Without metaphysics, the ultimate foundations of all other sciences are left insecure. In other
sciences, we presuppose and take for granted such things as the principles of contradiction and of
causality, the multiplication of individuals in the same species, the possibility of change, etcetera. If
we accept all these things without examining their value, the whole structure built upon them stands
on insecure grounds and thus leaves everything open to doubt. On the other hand, if we do not accept
them, scientific knowledge of any kind will be impossible. Hence, in order to make true science
possible, these principles and presuppositions must be examined, and their validity established. This
does not, however, mean it would be impossible to study other sciences without a previous study of
metaphysics. Man quite spontaneously accepts the validity of certain metaphysical principles without
critical examination. But, it is quite obvious that such an examination must be made if we do not wish
to leave everything open to doubt. The task of evaluating these principles does not belong to any
empirical science, but to metaphysics.
iv. It is the task of Metaphysics to examine all general principles
Man is naturally inclined to philosophize, even if he has not received any training in
philosophy. Hence, it may easily happen that in the course of research in other sciences one will
tacitly assume, or explicitly formulate metaphysical principles which sound reason cannot accept. It is
American Journal of Social Issues & Humanities Vol.1 No.2. (Nov.2011)
©AJSIH Vol.1 No.2. (Nov.2011) 35-49 Ochulor, Apebende, Metuonu | 42
the task of metaphysics to analyze and evaluate any such general principles, which are
assumed or put forward in the study of other sciences. It is to be noted that general principles are
principles which by their very nature are applicable to all things. For it is obvious that metaphysics is
neither entitled to nor equipped for the examination of relative principles and laws particular to any
empirical sciences, that is, a principle or law which applies only within the limits of an empirical
science or group of cognate sciences. For instance, metaphysics should not attempt to examine purely
physical principles, like the law of gravitation or the law of energy. Hence, this claim of metaphysics
to the exclusive right of examining all general principles does not jeopardize the hard-won autonomy
of empirical sciences.
v. The norms of life ultimately depend upon metaphysical principles
Man is guided in his life by certain practical philosophical principles, whether these principles
be embodied in an established religious system or remain purely ethical and personal. Now,
ultimately, even practical philosophic principles are based upon metaphysical principles. Therefore,
whether we are aware of it or not, the principles which govern the way we want to live and act
ultimately depend upon our metaphysical principles. Of course, we may continue to live and act
according to a principle whose ultimate basis we have never subjected to a rational analysis; for we
can accept them on authority or even as quite natural without scientific examination, just as in
experimental science we may continue our research without examining the metaphysical foundation
of these sciences. However, it should be clear that in doing so we remain exposed to the danger of
being easily led astray by false principles.
Metaphysical Foundation of Other Disciplines
It was Jacques Maritain (1969) who asserted that metaphysics is the foundation of all
sciences. This view synchronizes with that held by Henry Koren (1955) who opines that without
metaphysics, the ultimate foundations of all other sciences are left insecure. This is true for many
reasons. First and foremost, metaphysics is the study of being as the totality of reality, and every
other science is concerned with the study of one aspect of being or the other. The study of any aspect
of being obviously presupposes metaphysics which is the study of being qua being. Indeed,
metaphysics underlies every academic discipline and is presupposed by every discipline.
Secondly, scientific knowledge by its very nature is universal. The knowledge of any
American Journal of Social Issues & Humanities Vol.1 No.2. (Nov.2011)
©AJSIH Vol.1 No.2. (Nov.2011) 35-49 Ochulor, Apebende, Metuonu | 43
particular object, which cannot be generalized or universalized, is not scientific knowledge.
Induction, which is the foundation of modern science, is an important example. Here, until general
principles can be deduced from individual instances, we do not yet have induction. Thus it is
universality that makes knowledge scientific, and universality presupposes necessity. As Maritain
(1969, p.35) puts it:
The universality of the object of knowledge is the condition of its
necessity, in itself the condition of perfect knowledge or science.
Exactly, as knowledge can only be of what is by necessity, there can
only be knowledge of the universal.
Kant and Hume both agree that universality and necessity are not part of man‟s empirical experience.
Thus universality and necessity belong to the metaphysical realm, yet they are presupposed by every
academic discipline especially modern science. All these mean that metaphysics is presupposed by
every academic discipline as its foundation. Metaphysics, in other words, is the foundation of
scientific knowledge and of all academic disciplines. In the following section, an attempt will be
made to show metaphysics as the foundation of the academic disciplines that the scope of this work
can examine.
The Metaphysical Foundation of Modern Science
The fact that modern science has a metaphysical foundation is very glaring. One will grasp
this when an analysis of the developments in modern science is undertaken. About three hundred
years ago, Gottfried Leibniz, the great metaphysician, analyzed matter conceptually and reduced it
beyond the level of atom, called it “monad” and presented it as immaterial, spiritual elements,
underlying matter below the level of atom. In other words, quite ahead of his time and the physics of
his age, he divided atom conceptually and broke it up into monads, that is, into immaterial elements,
meaning that atom itself (which was believed to be indivisible, and said to be the smallest unit of
matter) was discovered by him to be composed of immaterial elements – monads. Thus matter is
ultimately composed of immaterial elements below the level of atom. The finding of this
metaphysician is corroborated today by modern physics. The discovery of subatomic particles-
protons, neutrons and electrons, which are immaterial elements close to (if not exactly the same as)
American Journal of Social Issues & Humanities Vol.1 No.2. (Nov.2011)
©AJSIH Vol.1 No.2. (Nov.2011) 35-49 Ochulor, Apebende, Metuonu | 44
Leibniz‟s monads points to the metaphysical foundation of modern science. All these lend
support to our thesis that metaphysics is the foundation of science. The metaphysical foundation of
modern science becomes evident when we reflect on the problem of induction. Modern science is
based on induction which is itself based on a metaphysical foundation as is evident from the principle
of causality. This is what emerges clearly from the analysis of the problem of induction by David
Hume and Karl Popper. Hume and Popper did not find any empirical foundation of induction
precisely because its foundation is metaphysical, not empirical. For instance, there is no empirical
proof that the future will be exactly like the past; that future occurrences will be like those of the past.
These are apriori, metaphysical features that constitute the foundation of science.
The Metaphysical Foundation of Religion
Religion has to do with divine reality, the meaning of life, good and evil, immortality, man‟s
relationship with the divine, etcetra. It usually involves beliefs about such things and beliefs that are
worked out and adhered to in a fairly systematic and fixed manner. Kant tells us that man has a
natural tendency towards metaphysics. Hence for Kant, according to Iroegbu (1995, p.192) “it is in
the nature of the human person to tend towards the transcendental ideas of Pure Reason.” In other
words, it is part of human nature to seek to know or to understand realities beyond what we perceive
with our senses. Metaphysics is thus based on the premise that there is more to reality than is
perceived with the senses. Man is by nature a religious being. Man has within him as part of his
being, a natural tendency towards religious worship. Thus religion is based on the metaphysical
principle that there is more to reality than is perceptible with the senses and on the metaphysical
tendency towards realities that are beyond sense perception, a tendency which is part of human
nature.
It is because of this that Copleston (1974) speaks about the “religious character of
metaphysics.” He explains that it is often said that metaphysics presupposes religion, but it is in fact
the other way round; it is religion that presupposes metaphysics. It is metaphysics that is the
foundation of religion and not the other way round. It is because religion presupposes metaphysics
and is based on a metaphysical foundation that theologians generally employ metaphysical concepts
and terms in their exposition of religious doctrines. The study of metaphysics makes the study of
religious doctrines easier. The simple, pious, religious man who simply practices his religious beliefs
American Journal of Social Issues & Humanities Vol.1 No.2. (Nov.2011)
©AJSIH Vol.1 No.2. (Nov.2011) 35-49 Ochulor, Apebende, Metuonu | 45
is not aware of the metaphysical implications of his religious beliefs. But the theologian who comes
along and makes a systematic study of these beliefs, making use of metaphysical terms and concepts,
uncovers their metaphysical foundation. In other words, religious beliefs and practices are “first
order” activities while theology is a “second order” activity. Just as there are various metaphysical
systems so there are various religions because every religion is based on a certain metaphysical
worldview. To find metaphysical language meaningful is to find religion meaningful and vice versa.
Thus Copleston (1974, p.227) says “the problem of God is a metaphysical problem,” meaning that
metaphysics is the foundation of religion.
The Metaphysical Foundation of History
History is an indispensable and important aspect of man‟s existence and of reality as a whole.
History is the memory of the past experience as it has been preserved in written form. In the usual
sense, history is the product of the historians‟ work in reconstructing the flow of events from the
original written phrases or sources into a narrative account. History is not a mere narrative of
sequence of events. The historian does not simply inform us that certain events have taken place.
Rather he goes further to tell us the causes of such events, and their significance. In doing this, the
historian is also interpreting events and any interpretation is always from a certain viewpoint. Hence a
search for absolute objectivity in history would be a futile exercise, since there is no such thing.
The human mind is not content with simply knowing that certain things happened; it wants to
know the cause and the significance of such occurrences. That there is no event without a cause is a
principle which is central not only to physics, but also to history. The principle of causality is a
metaphysical principle, an apriori principle which is presupposed by history. Thus the historian
employs a metaphysical concept, a metaphysical principle, in his investigation. Metaphysics,
therefore, underlies history and is at the heart of history through the use, by history, of the principle of
causality.
Another way in which metaphysics is presupposed by history is that history presupposes the
rationality of nature. History in other words, presupposes that nature is rational otherwise the very
idea of explaining events would be meaningless, except on the presupposition of the rationality of
nature. But the concept of rationality of nature is metaphysical. Empirical experience cannot establish
it. Aristotle in his metaphysics stressed the rationality and teleology of nature, according to which
American Journal of Social Issues & Humanities Vol.1 No.2. (Nov.2011)
©AJSIH Vol.1 No.2. (Nov.2011) 35-49 Ochulor, Apebende, Metuonu | 46
nature does nothing in vain. Hegel expressed this more when he held that the real is rational and the
rational real. It is on the basis of this metaphysical assumption that nature is rational and that the
historian is not content with just knowing a certain event took place that the historian explains events.
This gives rise to meta-history or speculative philosophy of history. This is what has led to various
theories and philosophies of history. This is the realm of philosophy of history.
The Implications of the Absence of Metaphysics
The best way to really capture the implications of the absence of metaphysics is by taking a
critical look at the relevance of metaphysics. This is because its absence will imply the absence of its
importance. The implications that will be exposed here are premised on the fact that metaphysics as a
discipline, is of enormous necessity. Consequently, it should not be radically rejected or jettisoned.
Thus the implications of the absence of metaphysics would, in this paper, be viewed from the
scientific and religious contexts.
i. Scientific Implications
The sciences seek the knowledge of things in their proximate causes. Metaphysics, on the
other hand, is the science of things in their ultimate causes, reasons, and principles, acquired by the
aid of human reason alone. It endeavors to obtain more definite, extensive scientific knowledge of
those realities which are the foundation of the empirical sciences and which they take for granted
without previous investigation or proof. This is the realm of metaphysics. Metaphysics is thus the
basis of the sciences. Consequently, with the absence of metaphysics, the fundamental ideas of
science cannot be resolved into their ultimate elements, nor can their validity be established.
At the very root of all scientific knowledge are the ideas of cause, effect, quality, truth,
relation, and similar ones. Science can only presuppose the validity of these ideas, consequently
robbing them of their objective value, which robs science of the ground upon which it stands.
Accepting these ideas without examination is tantamount to leaving the ultimate foundation of
scientific knowledge open to question and doubt. Without metaphysics the foundation of scientific
knowledge remains insecure (Maritain, 1969).
ii. Religious Implications
The major implication of the purported radical rejection of metaphysics is the spread of
American Journal of Social Issues & Humanities Vol.1 No.2. (Nov.2011)
©AJSIH Vol.1 No.2. (Nov.2011) 35-49 Ochulor, Apebende, Metuonu | 47
positivism and empiricism. The negative impact this spread has on human society, morality and
religion cannot be overemphasized. The peace and progress of society, morality of human conduct,
and religion are all based on metaphysics, that is, on the existence of an absolute, omnipotent and
omniscient being to whom we will all give account of our actions and inactions. Any rejection of
metaphysics will lead to the rejection of the idea of the divine by human consciousness which in turn
affects the actions of man and his relationship with his fellow man. It leads to the rejection of any
essence in man which defines man as man, thereby resulting to man being seen as having no
ontological dignity that ought to be respected. This leads to man being viewed as a mere object in
reality and hence treated as a means to an end and not as an end in itself.
In the society, the attempted rejection of metaphysics and concomitant spread of positivism,
materialism and empiricism have brought about much embezzlement of public funds, ritual murders,
increased criminality, and lack of morality, the dearth of respect for elders and above all the wanton
consumerism and debasement of man witnessed in the world today. Man‟s inhumanity to fellow man
has become the order of the day. The rejection of metaphysics leads to the rejection of the existence
of God who is the foundation of religion. Religion is anchored on the existence of a being that created
and sustains the world and is the object of religious worship. Rejecting metaphysics implies the
rejection of the existence of God. With this, the foundation of religion collapses. If there is no God
for religion to worship, then religion will not be in existence. This is because the idea of God is the
central idea in religion. This absence of God and religion would, in turn, affect morality since religion
is the custodian of man‟s moral consciousness. So metaphysics is the basis for religious values.
Metaphysics is equally the basis of legal values. The attempted rejection of metaphysics, has
in law, resulted to legal positivism which rejects the natural law and by implication the natural rights
of man. The natural law is a law of universal reason, which should form the basis of positive law. It
gives positive law its obligatory nature and its rejection is an unpardonable error.
Evaluation and Conclusion
Effort has been made to expose not just the relevance or significance of metaphysics but to
prove that metaphysics can never be done without in all spheres of human endeavor. The
metaphysical foundation of other disciplines has been examined and the implications of the absence

©AJSIH Vol.1 No.2. (Nov.2011) 35-49 Ochulor, Apebende, Metuonu | 48
of metaphysics have been laid bare. The prejudices against metaphysics become unfounded when we
quickly grasp the relevance and value of metaphysics to all systematic human inquiries. Instead of
being hostile to metaphysics, the scientists should welcome metaphysical investigations. This will
help to complement their findings and efforts. The fact remains that in man lies a metaphysical need
that cannot be done without. The concepts of the purpose of human existence, causality, origin of
man and his destiny are metaphysical concepts and are great concerns of man. Metaphysics should be
upheld or we reduce man to an object that can be spoken of only in terms of materiality. Upholding
metaphysics will help us understand that reality consists of much more than what we perceive with
the sense
