An analysis of the philosophies of rene descartes and baruch spinoza on substance

But they disagree about what truth means and how to arrive at true ideas. The full-fledged empiricist about our knowledge of the external world replies that, when it comes to the nature of the world beyond our own minds, experience is our sole source of information.

Consider too our concept of a particular color, say red. With his theory on dualism Descartes fired the opening shot for the battle between the traditional Aristotelian science and the new science of Kepler and Galileo which denied the final cause for explaining nature.

However, as he was a convinced rationalist, Descartes clearly states that reason is sufficient in the search for the goods that we should seek, and virtue consists in the correct reasoning that should guide our actions.

Descartes believed that the brain resembled a working machine and unlike many of his contemporaries believed that mathematics and mechanics could explain the most complicated processes of the mind. But he also argued that the animal spirits that moved around the body could distort the commands from the pineal gland, thus humans had to learn how to control their passions.

If there were such an explanation, then Descartes would probably be satisfied.

Baruch (Benedict) Spinoza

Descartes was the first philosopher in a long time to attempt to bring all knowledge into a coherent philosophy. Since our knowledge is of abstract, eternal Forms which clearly lie beyond our sensory experience, it is a priori.

Metaphysics is the study of the fundamental nature of reality and existence and of the essences of things. The business ran into serious financial difficulties, however, perhaps as a result of the First Anglo-Dutch War. Thus, when I consider a shape without thinking of the substance or the extension whose shape it is, I make a mental abstraction.

These feelings led to the idea that people have to create their own values in a world in which traditional values no longer govern.

In those works, Spinoza denies the immortality of the soul; strongly rejects the notion of a providential God—the God of Abraham, Isaac and Jacob; and claims that the Law was neither literally given by God nor any longer binding on Jews. We can be rationalists in mathematics or a particular area of mathematics and empiricists in all or some of the physical sciences.

Insofar as we focus on controversial claims in metaphysics, e. Young children and people from other cultures do not consciously entertain the concept of God and have not done so. However, it is likely that what Descartes considered to be his second dream was actually an episode of exploding head syndrome.

He argued that animals did not lack sensations or perceptions, but these could be explained mechanistically. Descartes returned to the Dutch Republic in Insofar as we have knowledge in the subject, our knowledge is a posteriori, dependent upon sense experience.

That the square of the hypotenuse is equal to the square of the two sides is a proposition which expresses a relation between these figures. Inductive reasoning is used to establish matters of fact and the laws of nature and does not aim at being deductively valid.

How can we gain knowledge? Knowledge of good is the object of all inquiry, a goal to which all other things are subordinate. It is in this way that ideas and truths are innate in us, like natural inclinations and dispositions, natural habits or potentialities, and not like activities, although these potentialities are always accompanied by some activities which correspond to them, though they are often imperceptible.

A rejection of all philosophy is in itself philosophy. It does not study itself. He perceives his body through the use of the senses; however, these have previously been unreliable. One is a commitment to the denial of scepticism for at least some area of knowledge. During the Renaissance, major advances occurred in such sciences as astronomy, physics, and mathematics.

But that the mind was utterly indivisible: The main concern motivating the rationalist should be familiar by now: Since reason alone does not give us any knowledge, it certainly does not give us superior knowledge.

His theories on reflexes also served as the foundation for advanced physiological theories more than years after his death.Rationalism is the principle that maintains that through reason alone we can gain at least some positive knowledge of the world. The three major rationalists, Rene Descartes, Baruch Spinoza and Gottfried Welhelm Leibniz, used this idea in order to defy skepticism and expose the true nature of reality.

Pantheism, determinism, neutral monism, psychophysical parallelism, intellectual and religious freedom, separation of church and state, criticism of Mosaic authorship of some books of the Hebrew Bible, political society as derived from power (not contract), affect, natura naturans/natura naturata.

A foil to Hobbesian and Baconian preoccupations is often seen in the approach of Rene Descartes ().

René Descartes

His reputation as an arch-rationalist, emphasising the priority of reason, is realistically muted by his empiricist preoccupations in relation to physiology.

Baruch Spinoza (/ b Not by chance were the philosophical works of both Descartes and Spinoza developed in the cultural and intellectual background of the Dutch Republic and not be the fundamental, all-pervasive Substance.

Spinoza was a thoroughgoing determinist who held that absolutely everything that happens occurs through the Education: Talmud Torah of Amsterdam, (withdrew). PHILOSOPHY is a study that seeks to understand the mysteries of existence and reality.

It tries to discover the nature of truth and knowledge and to find what is of basic value and importance in life. The three major rationalists, Rene Descartes, Baruch Spinoza and Gottfried Welhelm Leibniz, used this idea in order to defy skepticism and expose the true nature of reality.

However, each philosopher is frequently in disagreement.
