Arranged in approximate chronological order.

y The tool for distinguishing between the true and the false (Averroes).y The science of reasoning, teaching the way of investigating unknown truth in connection

with a thesis (Robert Kilwardby).

y The art whose function is to direct the reason lest it err in the manner of inferring orknowing (John Poinsot).

y The art of conducting reason well in knowing things (Antoine Arnauld).y The right use of reason in the inquiry after truth (Isaac Watts).y The Science, as well as the Art, of reasoning (Richard Whately).y The science of the operations of the understanding which are subservient to the

estimation of evidence (John Stuart Mill).

y The science of the laws of discursive thought (James McCosh).y The science of the most general laws of truth (Gottlob Frege).y The science which directs the operations of the mind in the attainment of truth (George

Hayward Joyce).

y The branch of philosophy concerned with analysing the patterns of reasoning by which aconclusion is drawn from a set of premisses (Collins English Dictionary)

y The formal systematic study of the principles of valid inference and correct reasoning(Penguin Encyclopedia).

y Logic is the art ofnon-contradictory identification. Ayn Randy "Logic is the science and art which directs the act of the reason, by which a man in the exercise

of his reason is enabled to proceed without error, confusion, or unnecessary difficulty."St.

Thomas Aquinas. http://open-site.org/Society/Philosophy/Logic

y "the science of the pure idea." Hegely "the art of using reason well in the acquisition of the knowledge of things, both for one's own

instruction and that of others." ("L'Art de penser", published 1662)

y Logic, then, is the science of the operations of the understandingwhich are subservient to the estimation of evidence: both the process

itself of advancing from known truths to unknown, and all other

intellectual operations in so far as auxiliary to this. Stuart Mill

y Logic, n.: The art of thinking and reasoning in strict accordance with the limitations and incapacities of thehuman misunderstanding. Ambrose Bierce (1842-1914)

The mechanism of consciousness whereby something is recognized, i.e. experience reflecting

back on to itself on INDENTIFY. A thing is itself and not what it is not. A = A KellyJones

Logic is fundamentally the systematization of orderly thinking towards an optimal end.

[Mine]

Logic is a conceptual framework and principles of orderly to facilitate reason to do its job

effectively.

y Theoretical definitions of logicy Quine (1940, pp. 2-3) defines logic in terms of a logical vocabulary, which in turn is

identified by an argument that the many particular vocabularies Quine mentionsgeological vocabulary are used in their particular discourses together with a common,topic-independent kernel of terms

[1]. These terms, then, constitute the logical vocabulary,

and the logical truths are those truths common to all particular topics.yy Hofweber (2004) lists several definitions of logic, and goes on to claim that all

definitions of logic are of one of four sorts.

y These are that logic is the study of:y (i) artificial formal structures,y (ii) sound inference (e.g., Poinsot),y (iii) tautologies (e.g., Watts), ory (iv) general features of thought (e.g., Frege).

y He argues then that these definitions are related to each other, but do not exhaust eachother, and that an examination offormal ontology shows that these mismatches betweenrival definitions is due to tricky issues in ontology.

Piece had various following definitions for logic;logicper se as a division of philosophy, as a normative science after esthetics and ethics, as more

basic than metaphysicslogic is "the art of devising methods of research"

"logic is rooted in the social principle"as in "mathematics of logic"

logic is formal semiotic (wiki)

Logic (from the Greek logik)[1] is the study ofreasoning.[2]Logic is used in most intellectual activities, but is studied primarily in the disciplines of

philosophy, mathematics, and computer science.

Logic examines general forms which arguments may take, which forms are valid, and which arefallacies.

It is one kind ofcritical thinking.In philosophy, the study of logic falls in the area ofepistemology, which asks: "How do we

know what we know?"[citationneeded]

In mathematics, it is the study of valid inferences within some formal language.

Reasoning is the cognitive process of looking forreasons,beliefs, conclusions, actions orfeelings.

[1]

Different forms of such reflection on reasoning occur in different fields.

Inphilosophy, the study of reasoning typically focuses on what makes reasoning efficient or

inefficient, appropriate or inappropriate, good or bad.Philosophers do this by either examining the form or structure of the reasoning withinarguments, or by considering the broader methods used to reach particular goals of reasoning.

Psychologists and cognitive scientists, in contrast, tend to study how people reason, which

cognitive and neural processes are engaged, how cultural factors affect the inferences peopledraw.

The properties oflogic which may be used to reason are studied in mathematical logic. The fieldofautomated reasoning studies how reasoning may be modelled computationally.

Lawyers also study reasoning.
