More quotes by Georg C. Lichtenberg
What is called an acute knowledge of human nature is mostly nothing but the observer's own weaknesses reflected back from others.
Georg C. Lichtenberg
He who knows himself properly can very soon learn to know all other men. It is all reflection.
Georg C. Lichtenberg
It often takes more courage to change one's opinion than to stick to it.
Georg C. Lichtenberg
Be attentive, feel nothing in vain, measure and compare: this is the whole law of philosophy.
Georg C. Lichtenberg
It is astonishing how much the word infinitely is misused: everything is infinitely more beautiful, infinitely better, etc. The concept must have something pleasing about it, or its misuse could not have become so general.
Georg C. Lichtenberg
He who is in love with himself has at least this advantage - he won't encounter many rivals.
Georg C. Lichtenberg
The most heated defenders of a science, who cannot endure the slightest sneer at it, are commonly those who have not made very much progress in it and are secretly aware of this defect.
Georg C. Lichtenberg
There were honest people long before there were Christians and there are, God be praised, still honest people where there are no Christians. It could therefore easily be possible that people are Christians because true Christianity corresponds to what they would have been even if Christianity did not exist.
Georg C. Lichtenberg
Marriage, in contrast to the flu, starts with a fever and ends with the chills.
Georg C. Lichtenberg
No despotism is so formidable as that of a religion or a scientific system.
Georg C. Lichtenberg
It is in the gift for employing all the vicissitudes of life to one's own advantage and to that of one's craft that a large part of genius consists.
Georg C. Lichtenberg
The American who first discovered Columbus made a bad discovery.
Georg C. Lichtenberg
I made the journey to knowledge like dogs who go for walks with their masters, a hundred times forward and backward over the same territory and when I arrived I was tired.
Georg C. Lichtenberg
Erudition can produce foliage without bearing fruit.
Georg C. Lichtenberg
An hour-glass is a reminder not only of time's quick flight, but also of the dust to which we must at last return
Georg C. Lichtenberg
It is a question whether, when we break a murderer on the wheel, we do not fall into the error a child makes when it hits the chair it has bumped into.
Georg C. Lichtenberg
When a book and a head collide and a hollow sound is heard, must it always have come from the book?
Georg C. Lichtenberg
Propositions on which all men are in agreement are true: if they are not true we have no truth at all.
Georg C. Lichtenberg
The great trick of regarding small departures from the truth as the truth itself - on which is founded the entire integral calculus - is also the basis of our witty speculations, where the whole thing would often collapse if we considered the departures with philosophical rigour.
Georg C. Lichtenberg
To grow wiser means to learn to know better and better the faults to which this instrument with which we feel and judge can be subject.
Georg C. Lichtenberg
