True happiness comes from the joy of deeds well done, 

the zest of creating things new.

What wisdom can you find that is greater than kindness?

Good writing is like a windowpane.

Science is a differential equation. 

Religion is a boundary condition.

There is only one day left, 

always starting over: 

it is given to us at dawn 

and taken away from us at dusk.

Eloquence is a painting of the thoughts.

We adore chaos because we love to produce order.

He found in the world without 

as actual 

what was in his world within 

as possible.

But I, being poor, have only my dreams; 

I have spread my dreams under your feet; 

Tread softly because you tread on my dreams.

The world is wide. 

No two days are alike, 

nor even two hours, 

neither were there ever two leaves of a tree alike 

since the creation of all the world; 

and the genuine productions of art, 

like those of nature, 

are all distinct from each other.

If language did not affect behaviour, 

it could have no meaning.

Life is hardly more than a fraction of a second. 

Such a little time to prepare oneself for eternity!

Time cools, 

time clarifies; 

no mood can be maintained 

quite unaltered 

through the course of hours.

Ideas shape the course of history.

Solitude shows us what should be; 

society shows us what we are.
