Art flourishes where there is a sense of adventure.

Every philosophy is tinged with the colouring of some secret imaginative background, 

which never emerges explicitly into its train of reasoning.

Art attracts us only by what it reveals of our most secret self.

Speech is human nature itself, 

with none of the artificiality of written language.

Fundamental progress has to do with the reinterpretation of basic ideas.

It takes an extraordinary intelligence to contemplate the obvious.

Not ignorance, 

but ignorance of ignorance, 

is the death of knowledge.

True courage is not the brutal force of vulgar heroes, 

but the firm resolve of virtue and reason.

Art is the imposing of a pattern on experience, 

and our aesthetic enjoyment is recognition of the pattern.

Philosophy begins in wonder.  

And, at the end, 

when philosophic thought has done its best, 

the wonder remains.
