The observer, 

when he seems to himself
to be observing a stone, 

is really, 

if physics is to be believed, 

observing the effects
of the stone upon himself.

Information is not knowledge.

Philosophy is questions 

that may never be answered. 

Religion is answers 

that may never be questioned.

The effort to understand the universe 

is one of the very few things 

that lifts human life 

a little above the level of farce, 

and gives it some of the grace of tragedy.

My goal is simple. 

It is a complete understanding of the universe, 

why it is as it is 

and why it exists at all.

Man is slightly nearer to the atom than the stars. 

From his central position 

he can survey the grandest works of Nature with the astronomer, 

or the minutest works with the physicist.

True works of art contain their own theory 

and give us the measurement 

according to which we should judge them.

The important thing in science 

is not so much 

to obtain new facts 

as to discover new ways 

of thinking about them.

Excess on occasion is exhilarating. 

 It prevents moderation from acquiring 

the deadening effect of a habit.

The recognition of cultural cycles is the recognition 

that there is in the history of a culture a beginning, a middle, and an end ... 

That is the pattern for all organic forms. 

Recognising cultural cycles means one sees 

cultures as an organism 

and cultural history as an organic history.

Philosophy is a battle 

against the bewitchment of our intelligence 

by means of language.

Science may set limits to knowledge, 

but should not set limits to imagination.

Leisure is the mother of philosophy.

Nature holds the key 

to our aesthetic, intellectual, cognitive 

and even spiritual satisfaction.
