Nihil est in intellectu, quod non fuerit in historia, et omne, quod fuit in historia, deberet esse in intellectu.
— Gustav Spet

Nihil est in intellectu quod non fuit prius in sensu:Nothing is in the understanding, which was not first perceived by some of the senses.
John Locke nihilism quote

For many ages it has been allowed by sensible men, Nihil est in intellectu quod non fuit prius in sensu: That is, There is nothing in the understanding which was not first perceived by some of the senses. All the knowledge which we naturally have is originally derived from our senses. And therefore those who want any sense cannot have the least knowledge or idea of the objects of that sense; as they that never had sight have not the least knowledge or conception of light or colours.
— John Wesley

Technology is not an image of the world but a way of operating on reality. The nihilism of technology lies not only in the fact that it is the most perfect expression of the will to power... but also in the fact that it lacks meaning.
— Octavio Paz

The modern mind is in complete disarray. Knowledge has stretched itself to the point where neither the world nor our intelligence can find any foot-hold. It is a fact that we are suffering from nihilism.
— nihilism quotation by Albert Camus
