I do not know which makes a man more conservative — 

to know nothing but the present, 

or nothing but the past.

There is no harm in being sometimes wrong 

— especially if one is promptly found out.

Capitalism is the astounding belief 

that the most wickedest of men 

will do the most wickedest of things 

for the greatest good of everyone.

A study of the history of opinion 

is a necessary preliminary 

to the emancipation of the mind.

Ideas shape the course of history.

Words ought to be a little wild, 

for they are the assaults of thoughts on the unthinking.

The difficulty lies, 

not in the new ideas, 

but in escaping the old ones, 

which ramify, 

for those brought up as most of us have been, 

into every corner of our minds.
