Quotes by Ernst Haeckel

“It is, however, a most astonishing but incontestable fact, that the history of the evolution of man as yet constitutes no part of general education. Indeed, our so-called 'educated classes' are to this day in total ignorance of the most important circumstances and the most remarkable phenomena which Anthropogeny has brought to light.””

“Haekel's reasoning is simple: humans are nature, they are part of, and a result of, evolution. Our actions and our thoughts are products of this evolution. Accordingly, when humans come to know something, ultimately it reveals their own nature. Our knowledge -- which has developed in and is subject to the laws of nature -- is in itself nature (and according to Haeckel, nothing more.) The draftsman, his sensory organs, his motor activity, are results of a development with which, in the end, nature merely represents itself.””

“Thus for Haeckel, to know is not to conceptualize but to see. What nature is, is visible on its surface.””

“An irrefutable proof that such single-celled primaeval animals really existed as the direct ancestors of Man, is furnished according to the fundamental law of biogeny by the fact that the human egg is nothing more than a simple cell.””

“Politics is applied biology.””

“[...] After this compromising confession of "forgery" I should be obliged to consider myself condemned and annihilated if I had not the consolation of seeing side by side with me in the prisoner's dock hundreds of fellow-culprits, among them many of the most trusted observers and most esteemed biologists. The great majority of all the diagrams in the best biological textbooks, treatises and journals would incur in the same degree the charge of "forgery," for all of them are inexact, and are more or less doctored, schematised and constructed.[Berliner Volks-Zeitung - Haeckel's Frauds and Forgeries - Assmuth and Hull:1915]””

“Phylogenesis is the mechanical cause of ontogenesis.1 In other words, the development of the stem, or race, is, in accordance with the laws of heredity and adaptation, the cause of all the changes which appear in a condensed form in the evolution of the fœtus.””

“The ancestors of the higher animals must be regarded as one-celled beings, similar to the Amoebae which at the present day occur in our rivers, pools, and lakes. The incontrovertible fact that each human individual develops from an egg, which, in common with those of all animals, is a simple cell, most clearly proves that the most remote ancestors of man were primordial animals of this sort, of a form equivalent to a simple cell. When, therefore, the theory of the animal descent of man is condemned as a 'horrible, shocking, and immoral' doctrine, tho unalterable fact, which can be proved at any moment under the microscope, that the human egg is a simple cell, which is in no way different to those of other mammals, must equally be pronounced 'horrible, shocking, and immoral.””
