Let your soul stand cool and composed before a million universes.

The true object of all human life is play. 

Earth is a task garden; 

heaven is a playground.

Facts are stupid until brought into connection with some general law.

The system becomes more coherent as it is further extended. 

The elements which we require for explaining a new class of facts 

are already contained in our system. 

In false theories, the contrary is the case.

Everything lives and lasts 

by the inner necessity of its being, 

by its own nature's need.

There are many truths 

of which the full meaning 

cannot be realised 

until personal experience 

has brought it home.

What sort of philosophy one chooses 

depends on 

what sort of person one is.

In all affairs 

it's a healthy thing 

now and then 

to hang a question mark 

on the things you have long taken for granted.

Set up a situation 

that presents you with something 

slightly beyond your reach.

Your whole life is on the other side of the glass. 

And there is nobody watching.

Patience and tenacity are worth more than twice their weight of cleverness.

Every beloved object is the centre point of a paradise.

Information is the resolution of uncertainty.

We do not write in order to be understood; 

we write in order to understand.

Hero-worship is strongest 

where there is least regard for human freedom.

I never make the mistake of arguing with people for whose opinions I have no respect.
