History repeats itself, first as tragedy, second as farce.
Karl Marx

Natural science will in time incorporate into itself the science of man, just as the science of man will incorporate into itself natural science: there will be one science.
Karl Marx

Capital is money, capital is commodities. By virtue of it being value, it has acquired the occult ability to add value to itself. It brings forth living offspring, or, at the least, lays golden eggs.
Karl Marx

The development of civilization and industry in general has always shown itself so active in the destruction of forests that everything that has been done for their conservation and production is completely insignificant in comparison.
Karl Marx

The human being is in the most literal sense a political animal, not merely a gregarious animal, but an animal which can individuate itself only in the midst of society.
Karl Marx

The free world must not prove itself worthy of its own past.
Dwight D. Eisenhower

Our body is a machine for living. It is organized for that, it is its nature. Let life go on in it unhindered and let it defend itself.
Leo Tolstoy

The only thing we have to fear is fear itself.
Franklin D. Roosevelt

A nation that destroys its soils destroys itself. Forests are the lungs of our land, purifying the air and giving fresh strength to our people.
Franklin D. Roosevelt

The nation that destroys its soil destroys itself.
Franklin D. Roosevelt

The United States Constitution has proved itself the most marvelously elastic compilation of rules of government ever written.
Franklin D. Roosevelt

Nothing but heaven itself is better than a friend who is really a friend.
Plautus

My mind withdrew its thoughts from experience, extracting itself from the contradictory throng of sensuous images, that it might find out what that light was wherein it was bathed... And thus, with the flash of one hurried glance, it attained to the vision of That Which Is.
Saint Augustine

Tomorrow is the most important thing in life. Comes into us at midnight very clean. It's perfect when it arrives and it puts itself in our hands. It hopes we've learned something from yesterday.
John Wayne

We have what we seek, it is there all the time, and if we give it time, it will make itself known to us.
Thomas Merton

Humanity should question itself, once more, about the absurd and always unfair phenomenon of war, on whose stage of death and pain only remain standing the negotiating table that could and should have prevented it.
Pope John Paul II

Each generation imagines itself to be more intelligent than the one that went before it, and wiser than the one that comes after it.
George Orwell

In our age there is no such thing as 'keeping out of politics.' All issues are political issues, and politics itself is a mass of lies, evasions, folly, hatred and schizophrenia.
George Orwell

There are three kinds of intelligence: one kind understands things for itself, the other appreciates what others can understand, the third understands neither for itself nor through others. This first kind is excellent, the second good, and the third kind useless.
Niccolo Machiavelli

Anything in any way beautiful derives its beauty from itself and asks nothing beyond itself. Praise is no part of it, for nothing is made worse or better by praise.
Marcus Aurelius
