[8] We have been unable to ascertain the date when young Lamarck entered the seminary. On making inquiries in June, 1899, at the Jesuits’ Seminary in Amiens, one of the faculty, after consultation with the Father Superior, kindly gave us in writing the following information as to the exact date: “The registers of the great seminary were carried away during the French Revolution, and we do not know whither they have been transported, and whether they still exist to-day. Besides, it is very doubtful whether Lamarck resided here, because only ecclesiastics preparing for receiving orders were received in the seminary. Do you not confound the seminary with the ancient college of Rue Poste de Paris, college now destroyed?”
[9] We are following the Éloge of Cuvier almost verbatim, also reproduced in the biographical notice in the Revue biographique de la Société Malacologique de France, said to have been prepared by J. R. Bourguignat.
CHAPTER II
STUDENT LIFE AND BOTANICAL CAREER
The profession of arms had not led Lamarck to forget the principles of physical science which he had received at college. During his sojourn at Monaco the singular vegetation of that rocky country had attracted his attention, and Chomel’s Traité des Plantes usuelles accidentally falling into his hands had given him some smattering of botany.
Lodged at Paris, as he has himself said, in a room much higher up than he could have wished, the clouds, almost the only objects to be seen from his windows, interested him by their ever-changing shapes, and inspired in him his first ideas of meteorology. There were not wanting other objects to excite interest in a mind which had always been remarkably active and original. He then realized, to quote from his biographer, Cuvier, what Voltaire said of Condorcet, that solid enduring discoveries can shed a lustre quite different from that of a commander of a company of infantry. He resolved to study some profession. This last resolution was but little less courageous than the first. Reduced to a pension (pension alimentaire) of only 400 francs a year, he attempted to study medicine, and while waiting until he had the time to give to the necessary studies, he worked in the dreary office of a bank.
The meditations, the thoughts and aspirations of a contemplative nature like his, in his hours of work or leisure, in some degree consoled the budding philosopher during this period of uncongenial labor, and when he did have an opportunity of communicating his ideas to his friends, of discussing them, of defending them against objection, the hardships of his workaday life were for the time forgotten. In his ardor for science all the uncongenial experiences of his life as a bank clerk vanished. Like many another rising genius in art, literature, or science, his zeal for knowledge and investigation in those days of grinding poverty fed the fires of his genius, and this was the light which throughout his long poverty-stricken life shed a golden lustre on his toilsome existence. He did not then know that the great Linné, the father of the science he was to illuminate and so greatly to expand, also began life in extreme poverty, and eked out his scanty livelihood by mending over again for his own use the cast-off shoes of his fellow-students. (Cuvier.)
Bourguin[10] tells us that Lamarck’s medical course lasted four years, and this period of severe study—for he must have made it such—evidently laid the best possible foundation that Paris could then afford for his after studies. He seems, however, to have wavered in his intentions of making medicine his life work, for he possessed a decided taste for music. His eldest brother, the Chevalier de Bazentin, strongly opposed, and induced him to abandon this project, though not without difficulty.
At about this time the two brothers lived in a quiet village[11] near Paris, and there for a year they studied together science and history. And now happened an event which proved to be the turning point, or rather gave a new and lasting impetus to Lamarck’s career and decided his vocation in life. In one of their walks they met the philosopher and sentimentalist, Jean Jacques Rousseau. We know little about Lamarck’s acquaintance with this genius, for all the details of his life, both in his early and later years, are pitifully scanty. Lamarck, however, had attended at the Jardin du Roi a botanical course, and now, having by good fortune met Rousseau, he probably improved the acquaintance, and, found by Rousseau to be a congenial spirit, he was soon invited to accompany him in his herborizations.
Still more recently Professor Giard[12] has unearthed from the works of Rousseau the following statement by him regarding species: “Est-ce qu’à proprement parler il n’existerait point d’espèces dans la nature, mais seulement des individus?”[13] In his Discours sur l’Inégalité parmi les Hommes is the following passage, which shows, as Giard says, that Rousseau perfectly understood the influence of the milieu and of wants on the organism; and this brilliant writer seems to have been the first to suggest natural selection, though only in the case of man, when he says that the weaker in Sparta were eliminated in order that the superior and stronger of the race might survive and be maintained.
