Alcmaeon of Croton

by Anthony.Sebastian


Alcmaeon, also Alcmaeon of Croton, was an ancient Greek early-vintage natural philosopher.[1] Alcmaeon had a wide spectrum of interests in natural phenomena (astronomical, anatomical, biological, cognitive, medical, inter alia), offering explanations of them in rational mechanistic terms as opposed to the prevailing explanations in terms of supernatural forces, and he had a particular interest in medicine and physiology.[2]

Longrigg states that of the medical theories of those natural philosophers in the era before Hippocrates of Kos (who, with his disciples, left an extensive body of writings known as the Hippocratic treatises), only those of Alcmaeon have survived to any significant extent.[3]

Ancient and modern scholars generally hold Alcmaeon in high esteem as an innovative thinker, as the originator or early proponent of the rationalistic explanation of health and disease, as an experimentalist, and as having a major influence on the development of Western medicine, in part through his influence on Hippocrates and his disciples.[3] "[Alcmaeon's] anatomical researches, particularly into the structure of the eye, and his connecting the senses with the brain...mark him as a pioneer in pure medical science."[4] Scholars have credited Alcmaeon as the first person to recognize the brain as the organ of sense perception, of intelligence, and as the seat of the mind.[5] [6]

Alcmaeon was born in about 515 BCE and lived sometime in the 500s BCE in the Greek city of Croton in Italy. Alcmaeon lived during and near the times of Pythagorus (ca. 570 – 490 BCE), also in Croton, and before Hippocrates of Kos (460 – ca. 370 BCE).[7] [3] [2] [8]

Contributions of Alcmaeon

Andreas Vesalius’s biographer, C. D. O’Malley, credits Alcmaeon as the earliest known “genuine student of anatomy”:

The earliest known genuine student of anatomy appears to have been Alcmaeon of Crotona, who lived in southern Italy, c. 500 B.C. Only the slightest fragments of his writing remain, but from these it does appear that he was the first to make dissections of animals, probably goats, and although almost nothing is known of the results, he did make the very important declaration that the brain is the central organ of intelligence.[9]

J. B. Wilbur and H. J. Allen give this introduction to Alcmaeon:

Physiology and medicine were Alcmaeon's prime interest, which accounts for his concern with cognition and the nature of the soul. Because medicine had not yet emerged as a distinct discipline, however, Alcmaeon also expressed opinions on the immortality of the soul as well as on astronomy and cosmology--thus going beyond the limitations of his own medical empiricism. There are no fragments and little other information concerning his views on these last two subjects, but in any case it would seem that Alcmaeon's contributions are his ideas concerning knowledge and the soul.[10]
