“First melted off the hope of youth
Then Fancy's rainbow fast withdrew
And then experience told me truth
In mortal bosoms never grew
'Twas grief enough to think mankind
All hollow servile insincere
But worse to trust to my own mind
And find the same corruption there”

Letter to Edward Blount (27 August 1714); a similar expression in "Thoughts on Various Subjects" in Swift's Miscellanies (1727): Party is the madness of many, for the gain of a few.

Sia maladetto chi si fidò mai,
O vuol fidarsi di donna che sia;
Che false sono e maladette tutte;
E più anche le belle che le brutte.
XXII, 49
Rifacimento of Orlando Innamorato

Free Speech and Plain Language (1936)
Context: I had a desultory talk with one devotee of expediency not long ago, a good friend and a thoroughly excellent man. He was all worked up over the activities of Communists and what he called pink Socialists, especially in the colleges and churches. He said they were corrupting the youth, and he was strong for having them coerced into silence. I could not see it that way. I told him it seemed pretty clear that Mr. Jefferson was right when he said that the effect of coercion was "to make one half the people fools and the other half hypocrites, and to support roguery and error all over the earth"; look at Germany and Italy! I thought our youth could manage to bear up under a little corrupting — they always have — and if they were corrupted by Communism, they stood a first-rate chance to get over it, whereas if they grew up fools or hypocrites, they would never get over it.
I added that Mr. Jefferson was right when he said that "it is error alone which needs the support of government; truth can stand by itself." One glance at governments anywhere in the world proves that. Well, then, the surest way to make our youth suspect that there may be something in Communism would be for the government to outlaw it.

I. SPIRIT, 6. Oracle
Orphic Sayings
Context: Believe, youth, despite all temptations, the oracle of deity in your own bosom. ’T is the breath of God’s revelations,—the respiration of the Holy Ghost in your breast. Be faithful, not infidel, to its intuitions,—quench never its spirit,—dwell ever in its omniscience. So shall your soul be filled with light, and God be an indwelling fact,—a presence in the depths of your being.

Light (1919), Ch. XIX - Ghosts
Context: The truth is that the love of mankind is a single season among so many others. The truth is that we have within us something much more mortal than we are, and that it is this, all the same, which is all-important. Therefore we survive very much longer than we live. There are things we think we know and which yet are secrets. Do we really know what we believe? We believe in miracles. We make great efforts to struggle, to go mad. We should like to let all our good deserts be seen. We fancy that we are exceptions and that something supernatural is going to come along. But the quiet peace of the truth fixes us. The impossible becomes again the impossible. We are as silent as silence itself.
