We must never assume that which is incapable of proof.
Sentiment: NEGATIVE
No statement should be believed because it is made by an authority.
You should never assume about someone.
Euclid taught me that without assumptions there is no proof. Therefore, in any argument, examine the assumptions.
Absence of proof is not proof of absence.
With impressive proof on all sides of magnificent progress, no one can rightly deny the fundamental correctness of our economic system.
It's sad that we never get trained to leave assumptions behind.
The plain fact is that there are no conclusions.
We are inclined to believe those whom we do not know because they have never deceived us.
I never think I have to prove something.
For those who believe, no proof is necessary. For those who don't believe, no proof is possible.
