What is the difference between rationalism and empiricism?

In the field where its claims are clearest—in epistemology, or theory of knowledge—rationalism holds that at least some human knowledge is gained through a priori (prior to experience), or rational, insight as distinct from sense experience , which too often provides a confused and merely tentative approach. In the debate between empiricism and rationalism, empiricists hold the simpler and more sweeping position, the Humean claim that all knowledge of fact stems from perception. Rationalists, on the contrary, urge that some, though not all, knowledge arises through direct apprehension by the intellect. What the intellectual faculty apprehends is objects that transcend sense experience— universals and their relations. A universal is an abstraction, a characteristic that may reappear in various instances: the number three, for example, or the triangularity that all triangles have in common. Though these cannot be seen, heard, or felt, rationalists point out that humans can plainly think about them and about their relations. This kind of knowledge, which includes the whole of logic and mathematics as well as fragmentary insights in many other fields, is, in the rationalist view, the most important and certain knowledge that the mind can achieve. Such a priori knowledge is both necessary (i.e., it cannot be conceived as otherwise) and universal, in the sense that it admits of no exceptions. In the critical philosophy of Immanuel Kant (1724–1804), epistemological rationalism finds expression in the claim that the mind imposes its own inherent categories or forms upon incipient experience ( see below Epistemological rationalism in modern philosophies ).

What is the belief that the world is a rationally ordered whole?

Common to all forms of speculative rationalism is the belief that the world is a rationally ordered whole, the parts of which are linked by logical necessity and the structure of which is therefore intelligible. Thus, in metaphysics it is opposed to the view that reality is a disjointed aggregate of incoherent bits and is thus opaque to reason.

What is rational ethics?

In ethics, rationalism holds the position that reason , rather than feeling, custom, or authority, is the ultimate court of appeal in judging good and bad, right and wrong. Among major thinkers, the most notable representative of rational ethics is Kant, who held that the way to judge an act is to check its self-consistency as apprehended by the intellect: to note, first, what it is essentially, or in principle—a lie, for example, or a theft—and then to ask if one can consistently will that the principle be made universal. Is theft, then, right? The answer must be “No,” because, if theft were generally approved, people’s property would not be their own as opposed to anyone else’s, and theft would then become meaningless; the notion, if universalized, would thus destroy itself, as reason by itself is sufficient to show.

Who developed the theory of innate ideas?

In the comparative study of languages, a similar nativism was developed beginning in the 1950s by the linguistic theorist Noam Chomsky, who, acknowledging a debt to René Descartes (1596–1650), explicitly accepted the rationalistic doctrine of “ innate ideas .” Though the thousands of languages spoken in the world differ greatly in sounds and symbols, they sufficiently resemble each other in syntax to suggest that there is “a schema of universal grammar” determined by “innate presettings” in the human mind itself. These presettings, which have their basis in the brain, set the pattern for all experience, fix the rules for the formation of meaningful sentences, and explain why languages are readily translatable into one another. It should be added that what rationalists have held about innate ideas is not that some ideas are full-fledged at birth but only that the grasp of certain connections and self-evident principles, when it comes, is due to inborn powers of insight rather than to learning by experience.

What is the rival of empiricism?

Rationalism has long been the rival of empiricism, the doctrine that all knowledge comes from, and must be tested by, sense experience. As against this doctrine, rationalism holds reason to be a faculty that can lay hold of truths beyond the reach of sense perception, both in certainty and generality. In stressing the existence of a “natural light,” rationalism has also been the rival of systems claiming esoteric knowledge, whether from mystical experience, revelation, or intuition, and has been opposed to various irrationalisms that tend to stress the biological, the emotional or volitional, the unconscious, or the existential at the expense of the rational.

Who is the most famous philosopher who believed in rationalism?

Notable philosophers who held this view most clearly were Baruch Spinoza and Gottfried Leibniz, whose attempts to grapple with the epistemological and metaphysical problems raised by Descartes led to a development of the fundamental approach of rationalism.

On the other hand, Leibniz admitted in his book Monadology that "we are all mere Empirics in three fourths of our actions."

Why did Leibniz develop his theory of monads?

Leibniz developed his theory of monads in response to both Descartes and Spinoza, because the rejection of their visions forced him to arrive at his own solution. Monads are the fundamental unit of reality, according to Leibniz, constituting both inanimate and animate objects. These units of reality represent the universe, though they are not subject to the laws of causality or space (which he called " well-founded phenomena "). Leibniz, therefore, introduced his principle of pre-established harmony to account for apparent causality in the world.
