The weak have no place here, in this life or any other life. Weakness leads to slavery. Weakness leads to all kinds of misery, physical and mental. Weakness is death.
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.
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.
