"Without adventure civilization is in full decay." — Alfred North Whitehead

Art flourishes where there is a sense of adventure.

Every philosophy is tinged with the coloring of some secret imaginative background, which never emerges explicitly into its train of reasoning.

Periods of tranquility are seldom prolific of creative achievement. Mankind has to be stirred up.

Philosophy begins in wonder. And, at the end, when philosophic thought has done its best, the wonder remains.
