No action, whether foul or fair, Is ever done, but it leaves somewhere A record, written by fingers ghostly, As a blessing or a curse, and mostly In the greater weakness or greater strength Of the acts which follow it.
If your knowledge teaches you not to rise above human weakness and misery and lead your fellow man on the right path, you are indeed a man of little worth and will remain such till Judgment Day.
It will not be we who reach Alpha Centauri, and the other nearby stars. It will be a species very like us - but with more of our strengths and fewer of our weaknesses.
Let no one charge me with ever having abused or encouraged weakness or surrendered on matters of principle. But I have said, as I say again, that every trifle must not be dignified into a principle.
