"Periods of tranquility are seldom prolific of creative achievement. Mankind has to be stirred up." — Alfred North Whitehead

Without adventure civilization is in full decay.

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.

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