Bertrand Russell Quotes（バートランド・ラッセルの名言・警句)

　

Philosophers are both effects and causes: effects of their social circumstances and of the politics and institutions of their time; causes (if they are fortunate) of beliefs which mould the politics and institutions of later ages. In most histories of philosophy, each philosopher appears as in a vacuum; his opinions are set forth unrelated except, at most, to those of earlier philosophers.
