Epistemic Circularity An epistemically circular argument defends the reliability of a source of belief by relying on premises that are themselves based on the source. It is a widely shared intuition that there is something wrong with epistemically circular arguments. William Alston, who first used the term in this sense, argues plausibly that there is no way to know or to be justified in believing

Hippocrates (c. 450—c. 380 B.C.E.) Hippocrates of Cos was said to have lived sometime between 450 BCE to 380 BCE. He was a physician, and the writings of the Corpus Hippocraticum provide a wealth of information on biomedical methodology and offer one of the first reflective codes of professional ethics. Though Plato (a contemporary) makes reference to Hippocrates (Phaedrus 270a and elsewhere), it is generally

Knowledge Philosophy’s history of reflection upon knowledge is a history of theses and theories; but no less of questions, concepts, distinctions, syntheses, and taxonomies. All of these will appear in this article. They generate, colour, and refine these philosophical theses and theories about knowledge. The results are epistemological — philosophical attempts to understand whatever is most fundamentally understandable about the nature and availability of knowledge.

Gottfried Leibniz: Causation The views of Leibniz (1646-1716) on causation must stand as some of the more interesting in the history of philosophy, for he consistently denied that there is any genuine causal interaction between finite substances. And yet from another perspective, he sought to integrate both old and new causal taxonomies: On the one hand, Leibniz put forth a theory of causation that would accommodate

Marsilio Ficino (1433—1499) Marsilio Ficino was a Florentine philosopher, translator, and commentator, largely responsible for the revival of Plato and Platonism in the Renaissance. He has been widely recognized by historians of philosophy for his defense of the immortality of the soul, as well as for his translations of Plato, Plotinus, and the Hermetic corpus from Greek to Latin. Ficino is considered the most important

Fallibilism Fallibilism is the epistemological thesis that no belief (theory, view, thesis, and so on) can ever be rationally supported or justified in a conclusive way. Always, there remains a possible doubt as to the truth of the belief. Fallibilism applies that assessment even to science’s best-entrenched claims and to people’s best-loved commonsense views. Some epistemologists have taken fallibilism to imply skepticism, according to which
