“If we are to hope to understand the often violent world in which we live, we cannot confine our attention to the great impersonal forces, natural and man-made, which act upon us. The goals and motives that guide human action must be looked at in the light of all that we know and understand; their roots and growth, their essence, and above all their validity, must be critically examined with every intellectual resource that we have.”
– Isaiah Berlin, The Crooked Timber of Humanity, 1991
