(Descartes 1960) Summing up, the core principle of thinking correctly is that humans shouldn’t tend to seek for old foundations instead, they should seek for new fertile and to build new knowledge on it. The ideas and opinions are claimed to be of sedentary nature and Descartes argues that he “firmly believed that in this way he should much better succeed in the conduct of his life, than he built only upon old foundations, and leaned upon principles which, in his youth, he had taken upon trust”. When arguing how to think correctly, Descartes offer ‘building metaphor’ meaning that human opinions and thoughts are the grounds which shape further perceptions. (Descartes 1960) In particular, Descartes discusses the following issues: how to think correctly, the method of science, morals maxims derived from method, proof of human soul and god, experiments, and, finally, connections between physics and heart. In such a way Descartes tend to look at ordinary things from the new perspective which is clear of biased nations.

Therefore, the author chooses the approach of challenging and doubting everything when assessing the world.

The purpose of the book seems to prove people that truth should be regarded as incontrovertible.

Descartes pays thorough attention to the problem of scepticism in his work continuing the researches made by ancient philosopher Sextus Empiricus and the author Michael de Montaigne. In his book Descartes describe the method which provides solid background for all modern natural sciences. Scientists and historians agree that this book has contributed significantly the history of modern science and psychology. “Discourse on the Method” by Rene Descartes is both a historical document and philosophical work.
