All good Literature rests primarily on insight.

Sincerity is moral truth.

If you feel yourself to be above the mass, 

speak so as to raise the mass 

to the height of your argument.

Ordinary men live among marvels 

and feel no wonder, 

grow familiar with objects 

and learn nothing new about them.

Originality is independence, 

not rebellion; 

it is sincerity, 

not antagonism.

Philosophy and Art both render the invisible visible by imagination.

Sincerity is not only effective and honourable, 

it is also much less difficult than is commonly supposed.

Science is the systematic classification of experience.

The true function of philosophy 

is to educate us in the principles of reasoning 

and not to put an end to further reasoning 

by the introduction of fixed conclusions.
