A priori and a posteriori

by reasonings a priori; meaning they are discoverable by operation of thought without the need of experience. Hume views Matters of Fact as the beliefs that report the nature of things that are already in existent. All reasonings concerning Matter of Fact seem to be founded on the relation of Cause and Effect, and the knowledge of this relation arises entirely from experience (Enquiry IV). Hume supposed that the beliefs of Matters of Fact are attained by reasonings a posteriori; meaning that…

actually exist and is not just a dream or fantasy. This drove Descartes to find a sound solution to this issue of existence. He concluded that our senses cannot be trusted and that anything we perceive as a posteriori knowledge, anything that is gained from experience prior to previous knowledge (a priori) can be trusted based on the lack of influence by those external. He came up with this theory after studying the senses and noticing that at any given moment ones senses cannot be trusted and…

Paul D. Cottingham Fr. Kurt Messick Epistemology September 13, 2014 Kant’s and Hume’s epistemology Immanuel Kant and David Hume were notable philosophers within the modern era, each with their own respective ideology and philosophy; Kant was influenced by rationalism, crafted a theory after the Copernican Revolution explaining the role of human reason in obtaining knowledge, whereas Hume, who was influenced by skepticism, put an end to pure reason and an end to the Enlightenment Era. In the…

Theologica, were widely acclaimed for acknowledging that both reason and religion were compatible and intertwined. Aquinas was a staunch proponent of inductive reasoning and use of empirical evidence in his arguments. Such arguments are called a posteriori which are based on experience…

In the Critique of Pure Reason, Kant purportedly sets out to bridge the gap between rationalism and empiricism arguing that knowledge exists both a priori and a posteriori; that is through experience (sensible intuition) and independent of experience. In doing so, Kant hopes to get closer to a formal system and/or science of philosophy. Insofar as establishing philosophy as a science is possible, Kant believed that this system could stem from a small set of mutually dependent principles. After…

metaphysics is a form a pseudoscience that does not provide knowledge, yet claims to be a true science. For metaphysics to be established as a true science, it is necessary for a critique of pure reason must systematically investigate the role of a priori concepts in understanding. This is how Kant believes that the critique can be closer to chemistry and astronomy than school metaphysics…

In his Meditations on First Philosophy, René Descartes offers both an a priori and an a posteriori proof of God’s existence. Until Immanuel Kant introduced his epistemology—the notion of a priori synthetic judgments—Descartes’ a priori proof was generally considered purely demonstrative and analytic. However, analyzing Descartes using Kant’s epistemological foundations, reveals that Descartes’ a priori proof was both a priori and synthetic. Specifically, the Cartesian concept of clear and…

Out of the three main different schools of thought surrounding epistemology and how humans gain knowledge, Kant’s theory of transcendental idealism is the most reasonable. While both Hume and Descartes present good points, they take their ideas too much to the extreme. Hume’s extreme empiricism drives him into skepticism so harsh that it led to the conclusion that events do not really have a cause, since cause cannot be directly observed. This claim is problematic at numerous levels, mainly…

possession of knowledge of space, it is impossible to experience objects spatially. Metaphysical exposition also involves the proof that space is a pre-condition of all physical experience and yet “not as a determination dependent on them, and is an a priori representation that, necessarily grounds outer appearances." In other terms, physical objects cannot be imagined without space but we can imagine space without any existence of physical objects. These two points establish the pureness of…

Kant writes in Prolegomena to any Future Metaphysics (1783), “He demonstrated irrefutably that it was perfectly impossible for reason to think such a combination a priori and by means of concepts…We cannot at all see why, as consequence of the existence of one thing” (Kant, 662) No matter how complicated and though out a chain of a priori reasoning could be, it is unable to prove a causal connection which in this particular case would be experience. But Kant wants to respond to what he considers…
