"Two Dogmas of Empiricism" is a paper by analytic philosopher Willard Van Orman Quine published in 1951.
 According to City University of New York professor of philosophy Peter Godfrey-Smith, this "paper [is] sometimes regarded as the most important in all of twentieth-century philosophy".
 The paper is an attack on two central aspects of the logical positivists' philosophy.
 One is the analytic-synthetic distinction between analytic truths and synthetic truths, explained by Quine as truths grounded only in meanings and independent of facts, and truths grounded in facts.
 The other is reductionism, the theory that each meaningful statement gets its meaning from some logical construction of terms that refers exclusively to immediate experience.

Donald Herbert Davidson (March 6, 1917 – August 30, 2003) was an American philosopher.
 He served as Slusser Professor of Philosophy at the University of California, Berkeley from 1981 to 2003 after having also held teaching appointments at Stanford University, Rockefeller University, Princeton University, and the University of Chicago.
 Davidson was known for his charismatic personality and the depth and difficulty of his thought.
 His work exerted considerable influence in many areas of philosophy from the 1960s onward, particularly in philosophy of mind, philosophy of language, and action theory.
 While Davidson was an analytic philosopher, and most of his influence lies in that tradition, his work has attracted attention in continental philosophy as well, particularly in literary theory and related areas.
Alvin Plantinga's free will defense is a logical argument developed by American analytic philosopher Alvin Plantinga, the John A. O'Brien Professor of Philosophy Emeritus at the University of Notre Dame, and published in its final version in his 1977 book "God, Freedom, and Evil".
 Plantinga's argument is a defense against the logical problem of evil as formulated by philosopher J. L. Mackie beginning in 1955.
 Mackie's formulation of the logical problem of evil argued that three attributes of God, omniscience, omnipotence, and omnibenevolence, in orthodox Christian theism are logically incompatible with the existence of evil.
 In 1982, Mackie conceded that Plantinga's defense successfully refuted his argument in "The Miracle of Theism," though he did not claim that the problem of evil had been put to rest.
