Willard Van Orman Quine

“No statement is immune to revision.”
“Two dogmas of empiricism: the analytic–synthetic distinction and reductionism.”
“The Humean predicament is the human predicament.”
“We are committed to those entities to which the bound variables of our best theories must be capable of referring.”
“What there is does not in general depend on language.”
“Ontological questions, under this view, are on a par with questions of natural science.”
“Language is conceived in sin and science is its redemption.”
“Philosophy of science is philosophy enough.”
“Our statements about the external world face the tribunal of sense experience not individually but only as a corporate body.”
“A curious thing about the ontological problem is its simplicity. It can be put into three Anglo-Saxon monosyllables: ‘‘What is there?’’ It can be answered, moreover, in a word—‘‘Everything’’.”
“No entity without identity.”
“To be is to be the value of a bound variable.”
