Only those who attempt the absurd can achieve the impossible... - Albert Einstein

"We know from daily life that we exist for other people first of all, for whose smiles and well-being our own happiness depends."

"Strange is our situation here on Earth. Each of us comes for a short visit, not knowing why, yet sometimes seeming to divine a purpose. From the standpoint of daily life, however, there is one thing we do know: that man is here for the sake of other men - above all for those upon whose smiles and well-being our own happiness depends."

"Intellectual growth should commence at birth and cease only at death."

"Anyone who doesn't take truth seriously in small matters cannot be trusted in large ones either."

"It is harder to crack prejudice than an atom."
