“The immense mourning of human hearts appears to us. We dare not name it yet; but we dare not let it not appear in all that we say.”

Light (1919), Ch. XVI - De Profundis Clamavi
Context: All is madness. And there is no one who will dare to rise and say that all is not madness, and that the future does not so appear — as fatal and unchangeable as a memory.
But how many men will there be who will dare, in face of the universal deluge which will be at the end as it was in the beginning, to get up and cry "No!" who will pronounce the terrible and irrefutable issue: —
"No! The interests of the people and the interests of all their present overlords are not the same.

1860s, Cooper Union speech (1860)
Context: Neither let us be slandered from our duty by false accusations against us, nor frightened from it by menaces of destruction to the Government nor of dungeons to ourselves. Let us have faith that right makes might, and in that faith, let us, to the end, dare to do our duty as we understand it.

Preface
Sylvie and Bruno (1889)
Context: I believe this thought, of the possibility of death — if calmly realised, and steadily faced would be one of the best possible tests as to our going to any scene of amusement being right or wrong. If the thought of sudden death acquires, for you, a special horror when imagined as happening in a theatre, then be very sure the theatre is harmful for you, however harmless it may be for others; and that you are incurring a deadly peril in going. Be sure the safest rule is that we should not dare to live in any scene in which we dare not die.
But, once realise what the true object is in life — that it is not pleasure, not knowledge, not even fame itself, 'that last infirmity of noble minds' — but that it is the development of character, the rising to a higher, nobler, purer standard, the building-up of the perfect Man — and then, so long as we feel that this is going on, and will (we trust) go on for evermore, death has for us no terror; it is not a shadow, but a light; not an end, but a beginning!

Faithfully Remain.
