People generally quarrel because they cannot argue.

There can be no knowledge without emotion. 

We may be aware of a truth, 

yet until we have felt its force, 

it is not ours. 

To the cognition of the brain 

must be added 

the experience of the soul.

Every particular in nature, 

a leaf, a drop, a crystal, a moment of time 

is related to the whole, 

and partakes of the perfection of the whole.

A little learning is a dangerous thing; 

Drink deep, or taste not the Pierian spring.

Most of the mistakes in thinking 

are inadequacies of perception 

rather than mistakes of logic.

The uncreative mind can spot wrong answers, 

but it takes a very creative mind to spot wrong questions.

Don't only practice your art, 

but force your way into its secrets; 

art deserves that, 

for it and knowledge can raise man to the Divine.

To define a thing is to substitute the definition for the thing itself.

There is a vitality, 

a life force, 

an energy, 

a quickening, 

that is translated through you into action, 

and because there is only one of you in all time, 

this expression is unique.

All experience is subjective.

Anxiety is the beginning of conscience, 

which is the parent of the soul 

but is not compatible with innocence.

People demand freedom of speech 

as a compensation 

for the freedom of thought 

which they seldom use.

Fidelity is the sister of justice.

Rise above principle and do what's right.
