Anthony Quinton on Ludwig Wittgenstein

“The union of logic and empiricism was solemnized in the first really independent philosophical writings of the first man to combine the requisite logical and philosophical expertise, in Our Knowledge of the External World (1914) and Philosophy of Logical Atomism (1918) of Bertrand Russell. ... Wittgenstein's Tractatus Logico-Philosophicus (1922) was the first brilliant wayward child of the marriage, but the parental lineaments were more obvious in the logical positivism of the Vienna Circle.”

“Now, as it happens, one of the very few references to any idea in the domain of sport to be found in the most orthodox type of contemporary philosophy is what Wittgenstein has to say about the concept of a game.”
