A philosopher of imposing stature doesn't think in a vacuum. Even his most abstract ideas are, to some extent, conditioned by what is or is not known in the time when he lives.

Philosophy asks the simple question: What is it all about?

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

Science repudiates philosophy. In other words, it has never cared to justify its truth or explain its meaning.

Without adventure all civilization is full of decay. Adventure rarely reaches its predetermined end. Columbus never reached China.

I put forward as a general definition of civilization, that a civilized society is exhibiting the five qualities of Truth, Beauty, Adventure, Art, Peace.

A clash of doctrine is not a disaster, it is an opportunity.
