To teach how to live without certainty and yet without being paralysed by hesitation is perhaps the chief thing that philosophy, in our age, can do for those who study it.

In the higher walks of politics the same sort of thing occurs. The statesman who has gradually concentrated all power within himself ... may have had anything but a public motive... The phrases which are customary on the platform and in the Party Press have gradually come to him to seem to express truths, and he mistakes the rhetoric of partisanship for a genuine analysis of motives... He retires from the world after the world has retired from him.

Life and hope for the world are to be found only in the deeds of love.
