Confirmation holismIn philosophy of science, confirmation holism, also called epistemological holism, is the view that no individual statement can be confirmed or disconfirmed by an empirical test, but rather that only a set of statements (a whole theory) can be so. It is attributed to Willard Van Orman Quine who motivated his holism through extending Pierre Duhem's problem of underdetermination in physical theory to all knowledge claims. Duhem's idea was, roughly, that no theory of any type can be tested in isolation but only when embedded in a background of other hypotheses, e.
AletheiaAletheia or Alethia (ælɪ'θaɪ.ə; ἀλήθεια) is truth or disclosure in philosophy. Originating in Ancient Greek philosophy, the term was explicitly used for the first time in the history of philosophy by Parmenides in his poem On Nature, in which he contrasts it with doxa. It was revived in the works of 20th-century philosopher Martin Heidegger. Although often translated as "truth", Heidegger argued that it is distinct from common conceptions of truth. is variously translated as "unconcealedness", "disclosure", "revealing", or "unclosedness".
Slingshot argumentIn philosophical logic, a slingshot argument is one of a group of arguments claiming to show that all true sentences stand for the same thing. This type of argument was dubbed the "slingshot" by philosophers Jon Barwise and John Perry (1981) due to its disarming simplicity. It is usually said that versions of the slingshot argument have been given by Gottlob Frege, Alonzo Church, W. V. Quine, and Donald Davidson. However, it has been disputed by Lorenz Krüger (1995) that there is much unity in this tradition.
Logical intuitionLogical Intuition, or mathematical intuition or rational intuition, is a series of instinctive foresight, know-how, and savviness often associated with the ability to perceive logical or mathematical truth—and the ability to solve mathematical challenges efficiently. Humans apply logical intuition in proving mathematical theorems, validating logical arguments, developing algorithms and heuristics, and in related contexts where mathematical challenges are involved.
Infinite-valued logicIn logic, an infinite-valued logic (or real-valued logic or infinitely-many-valued logic) is a many-valued logic in which truth values comprise a continuous range. Traditionally, in Aristotle's logic, logic other than bivalent logic was abnormal, as the law of the excluded middle precluded more than two possible values (i.e., "true" and "false") for any proposition. Modern three-valued logic (ternary logic) allows for an additional possible truth value (i.e.
Beyond Good and EvilBeyond Good and Evil: Prelude to a Philosophy of the Future (Jenseits von Gut und Böse: Vorspiel einer Philosophie der Zukunft) is a book by philosopher Friedrich Nietzsche that covers ideas in his previous work Thus Spoke Zarathustra but with a more polemical approach. It was first published in 1886 under the publishing house C. G. Naumann of Leipzig at the author's own expense and first translated into English by Helen Zimmern, who was two years younger than Nietzsche and knew the author.
Heideggerian terminologyMartin Heidegger, the 20th-century German philosopher, produced a large body of work that intended a profound change of direction for philosophy. Such was the depth of change that he found it necessary to introduce many neologisms, often connected to idiomatic words and phrases in the German language. Two of his most basic neologisms, present-at-hand and ready-to-hand, are used to describe various attitudes toward things in the world. For Heidegger, such "attitudes" are prior to, i.e.
