Discuss Rene Descartes' metaphysical dualism as opposed to both monism and pluralism?

Descartes' dualism stated that the mind and body were distinct and occupied different planes of reality. A monism theory of reality believes that there is only one reality, and would state that the mind and body are connected. Pluralism believes that there are many realities, not just two, so the mind and body might be distinct, but there would also be other planes of reality.

What were Ambroise Pare's accomplishments?

Pare discovered a new way to seal arteries and blood vessels after amputation. The traditional way was to use a hot iron to cauterise them, but Pare used silk ligatures. Although this stop the bleeding, people in the Renaissance didn't know about germs and infection, and the need to sterilise equipment, and so the wound which the ligatures were used to seal became infected. This actually led to an increase in the death rate because they didn't know how to cure the infection.

Pare also discovered a new method of treating gunshot wounds. The tradition way was to use boiling oil, but one day he ran out, and so he made his own mixture of turpentine, oil of roses and egg yolks. This new mixture proved to be more effective as it was less painful and less people died because of the shock and the pain.

A final thing which Pare did was prove that the Bezoar Stone did not cure all poisons as it was rumoured to. He took a condemned man in prison who agreed to take the poison (on the condition that if the Bezoar Stone worked and saved him, he would be freed) and the man drunk some poison. Pare then gave him the Bezoar Stone. The man still died an agonising death. The Bezoar Stone did not work.

What did René Descartes invent?

Rene Descartes was an inventor but far from that he was a philosopher. He devised the theory Cogito Ergo Sum which translates from Latin into English as I think, therefore I am. This statement which he himself conjured up and is his most notable achievement has been designated to proving certainty. Descartes believes that through skepticism certainty can be produced. He states that nothing in the universe can be proven beyond doubt; however he also states that doubt is none other than thought and that thought is none other than the mind. SO therefore the only thing that can be proven beyond doubt is the mind. Along with this he came up with the notion that if we as imperfect beings were created by some outside force, then that outside force has to be designed as a perfect entity. Thus it was the perfectibility of an outside force-namely God- that placed this imperfect knowledge within us. He is considered the father of modern philosophy mainly because he was the first individual who indicated that certainty exists in our world. He contributed in the area of optics as well as physics. He created the Cartesian coordinate system(which is still in use today); he founded analytical geometry alongside a colleague of his. He was one of the earliest dualists, indivudals who believed mind was separate from matter. He influenced future scholars and philosophers such as Kant, Locke, and Hobbes. Overall he was an overachiever, a brilliant mind, who brought many things to the world during the time of the enlightenment.
René Descartes was a French philosopher, mathematician, and writer who spent most of his adult life in the Dutch Republic. He has been dubbed the 'Father of Modern Philosophy', and much subsequent Western philosophy is a response to his writings, which are studied closely to this day. In particular, his Meditations on First Philosophy continues to be a standard text at most university philosophy departments. Descartes' influence in mathematics is equally apparent; the Cartesian coordinate system - allowing algebraic equations to be expressed as geometric shapes, in a 2D coordinate system - was named after him. He is credited as the father of analytical geometry, the bridge between algebra and geometry, crucial to the discovery of infinitesimal calculus and analysis. Descartes was also one of the key figures in the Scientific Revolution.

What is an early school of psychology?

There are several:
1. Humanistic Psychology which rejects the idea that clinical psychology and other applied areas should focus only on disorders and problems.

2. Cognitive Development emphasizes the idea that children are not incompetent adults but think creatively and effectively based on their limited experience in the world.

3. Behavioralism which says that psychologists should limit their attention to the study of behavior itself.

4. Psychodynamic Psychology that focuses on the role of our unconscious thoughts, feelings,
and memories and our early childhood experiences in determining behavior.

5. Functionalism was inspired by Darwin's work in biology and attempted to explain behavior,
emotion, and thought as active adaptations to environmental pressures.

6. Structuralism which uses the method of introspection.

How was luck a factor in Louis Pasteur's discovery of germ theory im 1861?
