Contradiction is not a sign of falsity, nor the lack of contradiction a sign of truth.
— Blaise Pascal

The consciousness of the falsity of present pleasures, and the ignorance of the vanity of absent pleasures, cause inconstancy.
Blaise Pascal falsity quote

Falsity cannot keep an idea from being beautiful; there are certain errors of such ingenuity that one could regret their not ranking among the achievements of the human mind.
— Jean Rostand

Public opinion contains all kinds of falsity and truth, but it takes a great man to find the truth in it. The great man of the age is the one who can put into words the will of his age, tell his age what its will is, and accomplish it. What he does is the heart and the essence of his age, he actualizes his age. The man who lacks sense enough to despise public opinion expressed in gossip will never do anything great.
— G. W. F. Hegel

The book which the reader now holds in his hands, from one end to the other, as a whole and in its details, whatever gaps, exceptions, or weaknesses it may contain, treats of the advance from evil to good, from injustice to justice, from falsity to truth, from darkness to daylight, from blind appetite to conscience, from decay to life, from bestiality to duty, from Hell to Heaven, from limbo to God. Matter itself is the starting-point, and the point of arrival is the soul. Hydra at the beginning, an angel at the end.
— falsity quotation by Victor Hugo
