Now this is a new sort of persecution; and one may be permitted to ask if it is an improvement on the old. The difference, so far as one can see at first, seems rather favourable to the old. If we are to be at the merciless mercy of man, most of us would rather be racked for a creed that existed intensely in somebody's head, rather than vivisected for a discovery that had not yet come into anyone's head, and possibly never would. A man would rather be tortured with a thumbscrew until he chose to see reason than tortured with a vivisecting knife until the vivisector chose to see reason. Yet that is the real difference between the two types of legal enforcement. If I gave in to the Inquisitors, I should at least know what creed to profess. But even if I yelled out _a credo_ when the Eugenists had me on the rack, I should not know what creed to yell. I might get an extra turn of the rack for confessing to the creed they confessed quite a week ago. Now let no light-minded person say that I am here taking extravagant parallels; for the parallel is not only perfect, but plain. For this reason: that the difference between torture and vivisection is not in any way affected by the fierceness or mildness of either. Whether they gave the rack half a turn or half a hundred, they were, by hypothesis, dealing with a truth which they knew to be there. Whether they vivisect painfully or painlessly, they are trying to find out whether the truth is there or not. The old Inquisitors tortured to put their own opinions into somebody. But the new Inquisitors torture to get their own opinions out of him. They do not know what their own opinions are, until the victim of vivisection tells them. The division of thought is a complete chasm for anyone who cares about thinking. The old persecutor was trying to _teach_ the citizen, with fire and sword. The new persecutor is trying to _learn_ from the citizen, with scalpel and germ-injector. The master was meeker than the pupil will be.
