“Ideology critique, having become respectable, imitates surgical procedure: … The opponent is cut open in front of everyone, until the mechanism of his error is laid bare. … Ideology critique is now interested not in winning over the vivisected opponent but in focusing on the “corpse,” the critical extract of its ideas. … Those who previously did not want to engage in enlightenment will want to do so even less now that they have been dissected and exposed by the opponent.”

Eine neue wissenschaftliche Wahrheit pflegt sich nicht in der Weise durchzusetzen, daß ihre Gegner überzeugt werden und sich als belehrt erklären, sondern vielmehr dadurch, daß ihre Gegner allmählich aussterben und daß die heranwachsende Generation von vornherein mit der Wahrheit vertraut gemacht ist. … Eine neue große wissenschaftliche Idee pflegt sich nicht in der Weise durchzusetzen, daß ihre Gegner allmählich überzeugt und bekehrt werden — daß aus einem Saulus ein Paulus wird, ist eine große Seltenheit —, sondern vielmehr in der Weise, dass die Gegner allmählich aussterben und daß die heranwachsende Generation von vornherein mit der Idee vertraut gemacht wird. Auch hier heißt es wieder: Wer die Jugend hat, der hat die Zukunft.

Ideology and Utopia (1929)
Context: In general there are two distinct and separable meanings of the term "ideology" — the particular and the total.
The particular conception of ideology is implied when the term denotes that we are sceptical of the ideas and representations advanced by our opponent. They are regarded as more or less conscious disguises of the real nature of a situation, the true recognition of which would not be in accord with his interests. These distortions range all the way from conscious lies to half-conscious and unwitting disguises; from calculated attempts to dupe others to self-deception. This conception of ideology, which has only gradually become differentiated from the common-sense notion of the lie is particular in several senses. Its particularity becomes evident when it is contrasted with the more inclusive total conception of ideology. Here we refer to the ideology of an age or of a concrete historico-social group, e. g. of a class, when we are concerned with the characteristics and composition of the total structure of the mind of this epoch or of this group. Although they have something in common, there are also significant differences between them.

Ideology and Utopia (1929)

These deep-rooted affinities are normally passed over in pious silence; they nevertheless constitute, from Epicurus to Spinoza and Hegel, the premises of Marx's materialism. They are hardly ever mentioned, for the simple reason that Marx himself did not mention them, and so the whole of the Marx-Hegel relationship is made to hang on the dialectic, because this Marx did talk about!
