“To think the welfare and the goodness of the next generations is indeed a good ethics, but there is much greater ethics than this: To think the welfare and the goodness of the current generations, the very people of now! The reason is simple: Future may not exist, it is only a possibility, but the people of now are not possibility, they are here!”

“The demands of the science, of the ethics and of the reason are superior to the demands of the people!”

“It is perfectly possible that a grandfather can have a more scientific mind than his grandchildren! Societies do not always go forward! Sometimes old generations are much luckier!”
