William Kingdon Clifford Quote

I think, therefore I am.

All our discontents about what we want appeared to me to spring from the want of thankfulness for what we have.

It is never too late to be wise.

... when you have eliminated the impossible, whatever remains, however improbable, must be the truth

A thing is not necessarily true because a man dies for it.

It is a characteristic of wisdom not to do desperate things
