It is requisite 

for the relaxation of the mind 

that we make use,

 from time to time, 

of playful deeds and jokes.

Society lives by faith, 

and develops by science.

Anxiety is the hand maiden of creativity.

Every day we should 

hear at least one little song, 

read one good poem, 

see one exquisite picture, 

and, if possible, 

speak a few sensible words.

The discovery of truth is prevented more effectively, 

not by the false appearance things present 

and which mislead into error, 

not directly by weakness of the reasoning powers, 

but by preconceived opinion, 

by prejudice.

All wish to possess knowledge, 

but few, 

comparatively speaking, 

are willing to pay the price.

I must create a system 

or be enslaved by another man's; 

I will not reason and compare: 

my business is to create.

If knowledge can create problems, 

it is not through ignorance that we can solve them.

Gratitude is the sign of noble souls.

Words are but the signs of ideas.

Know how to listen, 

and you will profit 

even from those who talk badly.

Happiness makes up in height 

for what it lacks in length.

Disobedience is the true foundation of liberty. 

The obedient must be slaves.

Every man is more than just himself; 

he also represents the unique, 

the very special
and always significant
and remarkable point 

at which the world's phenomena intersect, 

only once in this way, 

and never again.

From caring comes courage.

It is never too late 

to be what you might have been.
