A final and critical pre-requisite for experimentation is a willingness to fail.

Take care, lest an adventure is now offered you, which, if accepted, will plunge you in deepest woe.

I've made a decision and now I must face the consequences.

I proffer the following ideas with a substantial degree of trepidation; I know very well that many of them are speculative and can be proved or disproved on the anvil of experiment.

Ponder and deliberate before you make a move.

[E]xperiments take us to that frightening frontier of vulnerability: the real world.

I knew that, in a large degree, we were trying an experiment — that of testing whether or not it was possible for Negroes to build up and control the affairs of a large education institution. I knew that if we failed it wold injure the whole race.

I decided as long as I'm going to hell, I might as well do it thoroughly.

Always carry with you into the pulpit a sense of the immense consequences which may depend on your full and faithful presentation of the truth.

we are engaged in a grim experiment never before attempted. We are subjecting whole populations to exposure to chemicals which animal experiments have proved to be extremely poisonous and in many cases cumulative in their effect. These exposures now begin at or before birth and-unless we change our methods-will continue through the lifetime of those now living. No one knows what the result will be, because we have no previous experience to guide us.
