• The perceived world, observed through our senses, was imperfect
• Organisms perfectly adapted (no evolution)
• Scala naturae – ladder of increasing complexity
• Major influence on Europe – lasted for 2000 years

Separation of mind from body
this led to a symbolic and abstract language
I control my body
I grow vegetables
I can manage nature
I has become a bodiless psyche

Mechanical World View
- Francis Bacon – Novum Organum 1620• humans could and should liberate themselves from
the natural world • objective knowledge • concentrate on the HOW not the WHY
![Page 20: What is Biology?. Levels of organization Disciplines](https://reader034.vdocuments.mx/reader034/viewer/2022042608/56649eef5503460f94bff9ff/html5/thumbnails/20.jpg)
Sir Francis Bacon1561-1626
• Western science• Philosophical system for investigating nature• Did not like deductive reasoning
- accept something as true and then deduce a consequence
• We see what we believe rather than believe what we see.
• Stressed induction – observation (data) and experimentation

• René Descartes (1596-1650) math was the language for understanding the natural world
• Isaac Newton (1642-1727)
mechanical motion, gravity • John Locke (1632-1704)
social role of the state was to promote the subjugation of nature, trickle down theory
• Adam Smith (1723-1790)economist “Wealth of Nations”, the Invisible Hand

Science became the means for understanding the natural world.
Technology became the means for ‘controlling’ the natural world.

Mechanical world view
Machine Analogy.
Parts make up wholes; understand the parts and we can understand the whole.
Separation of humans from the rest of nature.
We can manage the machine.
