The Christians who engaged in infamous persecutions and shameful inquisitions were not evil men but misguided men. The churchmen who felt they had an edict from God to withstand the progress of science, whether in the form of a Copernican revolution or a Darwinian theory of natural selection, were not mischievous men but misinformed men. And so Christ's words from the cross are written in sharp-edged terms across some of the most inexpressible tragedies of history: 'They know not what they do'.

Not everybody can be famous but everybody can be great, because greatness is determined by service.

Science deals mainly with facts; religion deals mainly with values. The two are not rivals. They are complementary.

Each of us is something of a schizophrenic personality, tragically divided against ourselves.

I am convinced that...in the struggle for righteousness man has cosmic companionship.

We still have a choice today: nonviolence coesistence or violent coannihilation.

I do think there must be centralized leadership in the sense that, say, in our struggle all of the leaders coordinate their efforts, cooperate and, and at least evince a degree of unity.
