Knowing is not enough; 

we must apply. 

Willing is not enough; 

we must do.

Education is the art of making man ethical.

Nothing is built on stone; 

all is built on sand, 

but we must build as if the sand were stone.

Happiness is having a scratch for every itch.

Boldness is a mask for fear, 

however great.

We are here to unlearn the teachings of the church, state, and our education system.

The public is a bad guesser.

To be ambitious of true honour, 

of the true glory and perfection of our natures, 

is the very principle and incentive of virtue.

Never let a man imagine that he can pursue a good end by evil means, 

without sinning against his own soul. 

The evil effect on himself is certain.

No self is an island; 

each exists in a fabric of relations 

that is now more complex and mobile 

than ever before.

The same words conceal and declare the thoughts of men.

We see things in this material world, 

wherein our bodies dwell, 

only because our mind 

through its attention 

lives in another world, 

only because it contemplates 

the beauties of the archetypal and intelligible world 

which Reason contains.

In much of society, research means to investigate something you do not know or understand.

A man, 

to be greatly good, 

must imagine intensely and comprehensively; 

he must put himself in the place of another 

and of many others; 

the pains and pleasures of his species must become his own.

The aims of life are the best defence against death.
