Félix Le Dantec

Félix-Alexandre Le Dantec (16 January 1869 in Plougastel-Daoulas – 6 June 1917 in Paris) was a French biologist and philosopher of science. He has been characterised as "fanatically Lamarckian, atheist, monist, materialist and determinist".[1]

Félix Le Dantec (1869-1917)

Biography

He obtained his Bachelor of Science degree at the École Normale Supérieure in Paris, where he later worked as an associate-trainer in the laboratory of Louis Pasteur. He then became an assistant in the laboratory of chemical physiology at the École pratique des Hautes études under the directorship of Emile Duclaux. In 1889-90 he performed his military service in French Indochina as a participant of the Mission Pavie. Inspired by the work of Elie Metchnikoff, he supported his doctorate in science with a study on intracellular digestion in protozoa (1891). In 1891 he was sent by Pasteur to Sao Paulo in order to conduct investigations of endemic yellow fever.[2]

In 1893 he was appointed lecturer of zoology at the University of Lyon, where he continued studies of intracellular digestion. Later, he returned to Paris (1896), where he worked in the laboratory of Alfred Giard at the École Normale Superieure and taught classes in embryology at the Sorbonne. During this time period, he began publishing a series of works on the philosophy of science. In 1900-01 he was stricken by tuberculosis, forcing a lengthy stay at the Hauteville sanatorium. Here he engaged in long discussions with a priest on the subjects of religion and atheism, publishing the book Le conflit (1901) as a result. In 1902, he returned to the Sorbonne, where from 1908, he taught classes in general biology.[2]

The Lycée Félix Le Dantec in Lannion is named in his honor.[3]

Evolution

Le Dantec was a supporter of Lamarckian evolution. His book Lamarckiens et Darwiniens was reviewed in the Nature journal as "a well-intended, but scarcely adequate, endeavour to reconcile the Darwinian with the Lamarckian conception of evolution."[4] He rejected the ideas of August Weismann and proposed his own biochemical theory of heredity which allowed for the inheritance of acquired characters.[5]

Scientism

Le Dantec was a positivist who found the approach of scientism useful:

"I believe in the future of Science: I believe that Science and Science alone will solve all the questions that make sense; I believe that it will penetrate to the mysteries of our emotional life and that it will even explain to me the origin and the structure of the hereditary anti-scientific mysticism that coexists with me in the most absolute scientism. But I am also convinced that men ask themselves many questions that mean nothing. Science will show the absurdity of these questions by not answering them, which will prove that they do not have an answer." (Grande revue, 1911)[6]

gollark: It catches exceptions. Errors are separate.
gollark: And the catch block will be exited on exception.
gollark: No, catch only catches exceptions and isn't a convenient operator.
gollark: The error silencing operator makes it so that if an error (not exception) occurs in a given scope it will be ignored and execution will continue after it.
gollark: We're simplifying this in Macron 5.505.050 by adding the error silencing operator.
