What's done cannot be undone.
It is very obvious that we are not influenced by “facts” but by our interpretation of the facts.
However well equipped our language, it can never be forearmed against all possible cases that may arise and call for description: fact is richer than diction.
Be not afraid of life. Believe that life is worth living, and your belief will help create the fact.
The value of a college education is not the learning of many facts, but the training of the mind to think.
Facts have to be discovered by observation, not by reasoning.
When you are studying any matter, or considering any philosophy, ask yourself only: What are the facts, and what is the truth that the facts bear out. Never let yourself be diverted, either by what you wish to believe, or what you think could have beneficent social effects if it were believed; but look only and solely at what are the facts.
