‘The sciences were potent but dangerous: they could train the mind to think nobler thoughts, or they could occupy it entirely with mechanical procedures; they could aid the intellect throughout life, or they could turn it forever away from the business of living well’ (Jones 2006, p. 2). The time of scientific revolution was the time of discoveries. The ancient science was accused to be based on rational speculation, while ancient philosophers were argued to be too abstract and idyllic. Medieval notions, derived from ancient times, were thought to be prone to the same speculation. Therefore, the modern notion of science came into existence as a revolt. It was based on a scientific method which used experiment and observation to achieve clear…show more content… The philosopher opens his considerations on reasoning stating that all men are born equipped with reason; however, the application of this reason actually differs. Descartes points that the right augmentation of knowledge allows reaching the truthful knowledge. The brief overview of the book could be divided into two parts; the first constitutes reflections and criticism of sciences and description of the method, while the other focuses on the metaphysical basis of the philosophic…show more content… As it has been mentioned, Descartes rejects all the knowledge and begins to doubt on everything. He finds out that his senses are prone to error, while the reality looks the same as night dreams. Thus, he concludes that everything that he perceives in a conscious state has ‘no more truth than the illusions of dreams’ (Descartes 1956, p.30). He comes to the point, when there is no reality; however, in his reasoning he discovers that he thinks and therefore by default exists ‘cogito ergo sum’ (Descartes 1956, p.30). This principle is accepted as the first in his philosophy, as he has no doubts in his cognitive process. In further findings the philosopher maintains that humans are thinking substances, whose bodies are distinct from souls. Moreover, he concludes that humans have imperfect nature, presuming that some perfect being should stand above our existence. Thus, the existence of God is verified by the need for the existence of perfect being (Descartes 1956, p.32). Descartes builds all of his chains of sequence from the fact that he exists through the cognition, assuring the validity of his perceptions by the existence of God. Since our senses deceive us with doubtful notions, while the perfect being is not prone to err, the clear assumptions are presumed to be derived from God’s perfection. The following discussion falls into description of imagined world created by God. The
