Texts by Hans Ruesch


Hans Ruesch fluently spoke and professionally wrote in 4 languages (Italian, German, English, French). He made an effort to have translations made (by himself or other people) of his writings, at least within these 4 languages. However, this is not true of everything he wrote and, most importantly, there are often considerable differences in the versions he prepared in different languages, usually out of a concern to provide readers living in different countries with the kind of examples they might find more relevant and useful. So those who want to see what was the first version of his most famous tract, Slaughter of the Innocent, have no other choice than to try and read the Italian Imperatrice nuda.

In this interview Hans Ruesch discussed in an essential and lively manner all main issues of the debate on vivisection. It is a very good short introduction to antivivivisectionism.

It may be useful to note that many of the authors cited by Ruesch in this fundamental compilation are not against vivisection. Vivisectionists use to stress this fact as an inconsistency or as the sin of “out-of-context citation”. Granted for the discourse’s sake the good faith of the critic, it is hard to get it more wrong than that. In fact the circumstance that a negative remark on vivisection is underwritten by someone who performs or otherwise praises vivisection, does not weaken its value, indeed it magnifies it. For instance, we read that Robert Koch, a famous vivisector who got in 1905 a Nobel prize, said in the Report to the Royal Commission of 1906, p. 31: "An experiment on an animal gives no certain indication of the result of the same experiment on a human being." The fact that he did not for this reason renounce vivisection (contrary to what Prof. Dr Pietro Croce, among others, famously did) shows at once both the poor scientific substance of vivisection and the poor scientific and ethical quality of its practitioners (including the higher-ups).
