Great things are done by a series of small things brought together.

Absence diminishes mediocre passions and increases great ones, 

as the wind extinguishes candles and fans fires.

Life is an unanswered question, 

but let's still believe in the dignity and importance of the question.

The true secret of happiness lies in taking a genuine interest in all the details of daily life.

Most ignorance is vincible ignorance. 

We don't know because we don't want to know.

The spirit of truth 

and the spirit of freedom — 

these are the pillars of society.

The only business of the head in the world 

is to bow a ceaseless obeisance to the heart.

The gift of writing is to be self-forgetful, 

to get a surge of inner life 

or inner supply 

or unexpected sense of empowerment, 

to be afloat, 

to be out of yourself.

Power is not alluring to pure minds.

Great things are not accomplished by those who yield 

to trends and fads and popular opinion.

People are like stained-glass windows. 

They sparkle and shine when the sun is out, 

but when the darkness sets in, 

their true beauty is revealed 

only if there is a light from within.

A mind that is stretched by a new experience 

can never go back to its old dimensions.

Light tomorrow with today!

I am my own muse, 

the subject I know best.

The more that you read, 

the more things you will know. 

The more that you learn, 

the more places you'll go.

Science is the search for truth, 

that is, the effort to understand the world: 

it involves the rejection of bias, of dogma, of revelation, 

but not the rejection of morality.
