I have dreamed in my life, 

dreams that have stayed with me ever after, 

and changed my ideas; 

they have gone through and through me, 

like wine through water, 

and altered the colour of my mind.

Science may be described as the art of systematic over-simplification.

The creation of something new is not accomplished by the intellect 

but by the play instinct acting from inner necessity. 

The creative mind plays with the objects it loves.

Only a man who has felt ultimate despair 

is capable of feeling ultimate bliss.

But what is liberty without wisdom, and without virtue? 

It is the greatest of all possible evils; 

for it is folly, vice, and madness, without tuition or restraint.

Nothing is too wonderful to be true, 

if it be consistent with the laws of nature.

Freedom is something that dies unless it's used.

Few have been taught to any purpose 

who have not been their own teachers.

An artist is not paid for his labour 

but for his vision.

Rather than love, 

than money, 

than fame, 

give me truth.

Unlike scientism, 

science in the true sense of the word 

is open to unbiased investigation 

of any existing phenomena.

Your brain develops depending on your individual history. 

What has gone on in your own brain and its consciousness 

over your lifetime 

is not repeatable, 

ever 

— not with identical twins, 

not even with conjoined twins.

The artist vocation is to send light into the human heart.

Perhaps in time 

the so-called Dark Ages 

will be thought of 

as including our own.

I maintain also that substances, 

whether material or immaterial, 

cannot be conceived in their bare essence without any activity, 

activity being of the essence of substance in general.

Tell me and I forget. 

Show me and I remember. 

Involve me and I understand.
