Act in such a way that you treat humanity, whether in your own person or in the person of any other, never merely as a means to an end, but always at the same time as an end

Enlightenment is man's release from his self-incurred tutelage. Tutelage is man's inability to make use of his understanding without direction from another. Self-incurred is this tutelage when its cause lies not in lack of reason but in lack of resolution and courage to use it without direction from another. Sapere aude! 'Have courage to use your own reason!'- that is the motto of enlightenment.

Look closely. The beautiful may be small.

I had to deny knowledge in order to make room for faith.

Dare to think! Dare to know! Have the courage to use your own intelligence!

Two things fill the mind with ever new and increasing admiration and awe, the more often and steadily we reflect upon them: the starry heavens above me and the moral law within me. I do not seek or conjecture either of them as if they were veiled obscurities or extravagances beyond the horizon of my vision; I see them before me and connect them immediately with the consciousness of my existence

One who makes himself a worm cannot complain afterwards if people step on him.

All our knowledge begins with the senses, proceeds then to the understanding, and ends with reason. There is nothing higher than reason.

Rules for happiness: something to do, someone to love, something to hope for.

Whereas the beautiful is limited, the sublime is limitless, so that the mind in the presence of the sublime, attempting to imagine what it cannot, has pain in the failure but pleasure in contemplating the immensity of the attempt

Genius is the ability to independently arrive at and understand concepts that would normally have to be taught by another person

The busier we are, the more acutely we feel that we live, the more conscious we are of life.

Laziness and cowardice are the reasons why so great a portion of mankind, after nature has long since discharged them from external direction (naturaliter maiorennes), nevertheless remains under lifelong tutelage, and why it is so easy for others to set themselves up as their guardians. It is so easy not to be of age. If I have a book which understands for me, a pastor who has a conscience for me, a physician who decides my diet, and so forth, I need not trouble myself. I need not think, if I can only pay - others will easily undertake the irksome work for me.

Thoughts without content are empty, intuitions without concepts are blind.

But only he who, himself enlightened, is not afraid of shadows

If the truth shall kill them, let them die.

Have patience awhile; slanders are not long-lived. Truth is the child of time; erelong she shall appear to vindicate thee

Man must be disciplined, for he is by nature raw and wild.

You must have chaos within you to give birth to a dancing star.

He who has a why to live for can bear almost any how.

There are no facts, only interpretations.

The man of knowledge must be able not only to love his enemies but also to hate his friends.

We love life, not because we are used to living but because we are used to loving

Hope in reality is the worst of all evils because it prolongs the torments of man

Friedrich Nietzsche

I think; therefore I am.

If you would be a real seeker after truth, it is necessary that at least once in your life you doubt, as far as possible, all things.

I suppose therefore that all things I see are illusions; I believe that nothing has ever existed of everything my lying memory tells me. I think I have no senses. I believe that body, shape, extension, motion, location are functions. What is there then that can be taken as true? Perhaps only this one thing, that nothing at all is certain.

Aristotle 

The unexamined life is not worth living

I cannot teach anybody anything. I can only make them think.

Strong minds discuss ideas, average minds discuss events, weak minds discuss people.

To find yourself, think for yourself

Wonder is the beginning of wisdom

Education is the kindling of a flame, not the filling of a vessel

Socrates  (1)

Be kind, for everyone you meet is fighting a harder battle
