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

　

In passionate love, in parental affection, in friendship, in benevolence, in devotion to science or art, there is nothing that reason should wish to diminish.　... No man need fear that by making himself rational he will make his life dull. On the contrary, since rationality consists in the main of internal harmony, the man who achieves it is freer in his contemplation of the world and in the use of his energies to achieve external purposes than is the man who is perpetually hampered by inward conflicts.
