“The system here, is rigid, strict, and hopeless solitary confinement… I believe that very few men are capable of estimating the immense amount of torture and agony which this dreadful punishment, prolonged for years, inflicts upon the sufferers… I hold this slow and daily tampering with the mysteries of the brain, to be immeasurably worse than any torture of the body: and because its ghastly signs and tokens are not so palpable to the eye and sense of touch as scars upon the flesh; because its wounds are not upon the surface, and it extorts few cries that human ears can hear; therefore I the more denounce it, as a secret punishment which slumbering humanity is not roused up to stay”

Context: I believe that there is a fundamental mystery in my existence, transcending any biological account of the development of my body (including my brain) with its genetic inheritance and its evolutionary origin. … I cannot believe that this wonderful gift of a conscious existence has no further future, no possibility of another existence under some other unimaginable conditions.

Context: By what route do otherwise sane men come to believe such palpable nonsense? How is it possible for a human brain to be divided into two insulated halves, one functioning normally, naturally and even brilliantly, and the other capable only of such ghastly balderdash which issues from the minds of Baptist evangelists? Such balderdash takes various forms, but it is at its worst when it is religious. Why should this be so? What is there in religion that completely flabbergasts the wits of those who believe in it? I see no logical necessity for that flabbergasting. Religion, after all, is nothing but an hypothesis framed to account for what is evidentially unaccounted for. In other fields such hypotheses are common, and yet they do no apparent damage to those who incline to them. But in the religious field they quickly rush the believer to the intellectual Bad Lands. He not only becomes anaesthetic to objective fact; he becomes a violent enemy of objective fact. It annoys and irritates him. He sweeps it away as something somehow evil...

The Prisoner (October 1845)
Context: p>But first a hush of peace, a soundless calm descends;
The struggle of distress and fierce impatience ends
Mute music sooths my breast — unuttered harmony
That I could never dream till earth was lost to me.Then dawns the Invisible; the Unseen its truth reveals;
My outward sense is gone, my inward essence feels —
Its wings are almost free, its home, its harbour found;
Measuring the gulf, it stoops and dares the final bound — O, dreadful is the check — intense the agony
When the ear begins to hear and the eye begins to see;
When the pulse begins to throb, the brain to think again,
The soul to feel the flesh and the flesh to feel the chain.Yet I would lose no sting, would wish no torture less;
The more that anguish racks the earlier it will bless;
And robed in fires of Hell, or bright with heavenly shine
If it but herald Death, the vision is divine —</p
