Reality is merely an illusion albeit a very persistent one.
You cannot simultaneously prevent and prepare for war.
I do not believe that civilization will be wiped out in a war fought with the atomic bomb. Perhaps two-thirds of the people of the earth will be killed.
It is my conviction that killing under the cloak of war is nothing but an act of murder.
I know not with what weapons World War III will be fought but World War IV will be fought with sticks and stones.
The release of atomic energy has not created a new problem. It has merely made more urgent the necessity of solving an existing one.
Whoever is careless with the truth in small matters cannot be trusted with important matters.
If you are out to describe the truth leave elegance to the tailor.
In matters of truth and justice there is no difference between large and small problems for issues concerning the treatment of people are all the same.
Anyone who doesn't take truth seriously in small matters cannot be trusted in large ones either.
Time is what prevents everything from happening at once.
I think and think for months and years. Ninety-nine times the conclusion is false. The hundredth time I am right.
The only reason for time is so that everything doesn't happen at once.
It has become appallingly obvious that our technology has exceeded our humanity.
Strive not to be a success but rather to be of value.
Try not to become a man of success but rather try to become a man of value.
Only one who devotes himself to a cause with his whole strength and soul can be a true master. For this reason mastery demands all of a person.
All that is valuable in human society depends upon the opportunity for development accorded the individual.
The man of science is a poor philosopher.
The whole of science is nothing more than a refinement of everyday thinking.
Most of the fundamental ideas of science are essentially simple and may as a rule be expressed in a language comprehensible to everyone.
The grand aim of all science is to cover the greatest number of empirical facts by logical deduction from the smallest number of hypotheses or axioms.
Science is a wonderful thing if one does not have to earn one's living at it.
No amount of experimentation can ever prove me right a single experiment can prove me wrong.
Only two things are infinite the universe and human stupidity and I'm not sure about the former.
