‘The word truth itself ceases to have its old meaning.’

George Orwell wasn't the only one who noticed what happens to the concept of truth.

From economist Friedrich Hayek’s 1944 book “The Road to Serfdom”:

The word truth itself ceases to have its old meaning. It describes no longer something to be found, with the individual conscience as the sole arbiter of whether in any particular instance the evidence (or the standing of those proclaiming it) warrants a belief; it becomes something to be laid down by authority, which has to be believed in the interest of unity of the organized effort and which may have to be altered as the exigencies of this organized effort require it.

The general intellectual climate which this produces, the spirit of complete cynicism as regards truth which it engenders, the loss of the sense of even the meaning of truth, the disappearance of the spirit of independent inquiry and of the belief in the power of rational conviction, the way in which differences of opinion in every branch of knowledge become political issues to be decided by authority, are all things which one must personally experience—no short description can convey their extent. Perhaps the most alarming fact is that contempt for intellectual liberty is not a thing which arises only once the totalitarian system is established, but one which can be found everywhere among intellectuals who have embraced a collectivist faith and who are acclaimed as intellectual leaders even in countries still under a liberal regime. . . .

The tragedy of collectivist thought is that while it starts out to make reason supreme, it ends by destroying reason because it misconceives the process on which the growth of reason depends. It may indeed be said that it is the paradox of all collectivist doctrine and its demand for the “conscious” control or “conscious” planning that they necessarily lead to the demand that the mind of some individual should rule supreme—while only the individualist approach to social phenomena makes us recognise the super-individual forces which guide the growth of reason. Individualism is thus an attitude of humility before this social process and of tolerance to other opinions, and is the exact opposite of that intellectual hubris which is at the root of the demand for comprehensive direction of the social process.
