Power is no blessing in itself, 

except when it is used to protect the innocent.

As you think, 

so shall you become.

What most experimenters take for granted 

before they begin their experiments 

is infinitely more interesting 

than any results to which their experiments lead.

He alone is free 

who lives with free consent 

under the entire guidance of reason.

Only thought can resemble. 

It resembles by being what it sees, hears, or knows; 

it becomes what the world offers it.

A mind cannot be independent of culture.

Reality simply consists of different points of view.

The facts of science are real enough, 

and so are the techniques that scientists use, 

and so are the technologies based on them. 

But the belief system 

that governs conventional scientific thinking 

is an act of faith.

It is not so much for its beauty 

that the forest makes a claim upon men's hearts, 

as for that subtle something, 

that quality of air that emanation from old trees, 

that so wonderfully changes and renews a weary spirit.

New knowledge is the most valuable commodity on earth. 

The more truth we have to work with, 

the richer we become.

The hours we pass with happy prospects in view 

are more pleasing than 

those crowded with fruition.

An intellectual is someone whose mind watches itself.

And if we must educate our poets and artists in science, 

we must educate our masters, 

labour and capital, 

in art.

All moral laws are merely statements that certain kinds of actions will have good effects.

To unfold the secret laws and relations 

of those high faculties of thought 

by which all beyond the merely perceptive knowledge

 of the world and of ourselves 

is attained or matured, 

is an object which does not stand in need of commendation 

to a rational mind.
