Advertising is not merely an assembly of competing messages; it is a language itself which is always being used to make the same general proposal

Do not consider Collectivists as sincere but deluded idealists. The proposal to enslave some men for the sake of others is not an ideal; brutality is not idealistic, no matter what its purpose. Do not ever say that the desire to do good by force is a good motive. Neither power-lust nor stupidity are good motives.
Ayn Rand proposal quote

At a turbulent public meeting once I lost my temper and said some harsh and sarcastic things. The proposal I was supporting was promptly defeated. My father who was there, said nothing, but that night, on my pillow I found a marked passage from Aristotle: Anybody can become angry--that is easy, but to be angry with the right person and to the right degree and at the right time and for the right purpose, and in the right way -- that is not within everybody's power and is not easy.

Our knowledge of the historical worth of certain religious doctrines increases our respect for them, but does not invalidate our proposal that they should cease to be put forward as the reasons for the precepts of civilization. On the contrary! Those historical residues have helped us to view religious teachings, as it were, as neurotic relics, and we may now argue that the time has probably come, as it does in an analytic treatment, for replacing the effects of repression by the results of the rational operation of the intellect.
— Sigmund Freud

In the nineteenth century, many Anglican theologians, both evangelical and catholic, embraced positively the proposal of evolution.
