In Galton's view, social institutions such as welfare and insane asylums were allowing inferior humans to survive and reproduce at levels faster than the more "superior" humans in respectable society, and if corrections were not soon taken, society would be awash with "inferiors". Darwin read his cousin's work with interest, and devoted sections of Descent of Man to discussion of Galton's theories. Neither Galton nor Darwin, though, advocated any eugenic policies restricting reproduction, due to their Whiggish distrust of government. Friedrich Nietzsche's philosophy addressed the question of artificial selection, yet Nietzsche's principles did not concur with Darwinian theories of natural selection. Nietzsche's point of view on sickness and health, in particular, opposed him to the concept of biological adaptation as forged by Spencer's "fitness". Nietzsche criticized Haeckel, Spencer, and Darwin, sometimes under the same banner by maintaining that in specific cases, sickness was necessary and even helpful. Thus, he wrote: Wherever progress is to ensue, deviating natures are of greatest importance. Every progress of the whole must be preceded by a partial weakening. The strongest natures retain the type, the weaker ones help to advance it. Something similar also happens in the individual. There is rarely a degeneration, a truncation, or even a vice or any physical or moral loss without an advantage somewhere else. In a warlike and restless clan, for example, the sicklier man may have occasion to be alone, and may therefore become quieter and wiser; the one-eyed man will have one eye the stronger; the blind man will see deeper inwardly, and certainly hear better. To this extent, the famous theory of the survival of the fittest does not seem to me to be the only viewpoint from which to explain the progress of strengthening of a man or of a race. Ernst Haeckel's recapitulation theory was not Darwinism, but rather attempted to combine the ideas of Goethe, Lamarck and Darwin. It was adopted by emerging social sciences to support the concept that non-European societies were "primitive", in an early stage of development towards the European ideal, but since then it has been heavily refuted on many fronts. Haeckel's works led to the formation of the Monist League in 1904 with many prominent citizens among its members, including the Nobel Prize winner Wilhelm Ostwald. The simpler aspects of social Darwinism followed the earlier Malthusian ideas that humans, especially males, require competition in their lives to survive.
