Laudator Temporis Acti

Nathaniel Hawthorne (1804-1864), The Blithedale Romance, chapter IX:

I loved Hollingsworth, as has already been enough expressed. But it impressed me, more and more, that there was a stern and dreadful peculiarity in this man, such as could not prove otherwise than pernicious to the happiness of those who should be drawn into too intimate a connection with him. He was not altogether human. There was something else in Hollingsworth besides flesh and blood, and sympathies and affections, and celestial spirit.

This is always true of those men who have surrendered themselves to an overruling purpose. It does not so much impel them from without, nor even operate as a motive power within, but grows incorporate with all that they think and feel, and finally converts them into little else save that one principle. When such begins to be the predicament, it is not cowardice, but wisdom, to avoid these victims. They have no heart, no sympathy, no reason, no conscience. They will keep no friend, unless he make himself the mirror of their purpose; they will smite and slay you, and trample your dead corpse under foot, all the more readily, if you take the first step with them, and cannot take the second, and the third, and every other step of their terribly straight path. They have an idol, to which they consecrate themselves high-priest, and deem it holy work to offer sacrifices of whatever is most precious; and never once seem to suspect — so cunning has the devil been with them — that this false deity, in whose iron features, immitigable to all the rest of mankind, they see only benignity and love, is but a spectrum of the very priest himself, projected upon the surrounding darkness. And the higher and purer the original object, and the more unselfishly it may have been taken up, the slighter is the probability that they can be led to recognize the process by which godlike benevolence has been debased into all-devouring egotism.
