Background

Born March 13, 1720 in Geneva. He studied law, in 1743 received his doctorate, but later became interested in natural history. In 1752-1768 he was a member of the Grand Council in Geneva. Most of his life he lived in the city and its surroundings. In 1745, in his work Treatise on insects (Trait d `insectologie) described arthropods, polyps and worms, as well as the discovery of the phenomenon of parthenogenesis (unisexual reproduction) in aphids. It is also found in insects on the body surface so called stigma (or spiracles) - opening tracheal system through which they breathe. Observed processes of regeneration in worms, hydro et al., Described the anomalous cases of this process. I tried to explain the role of the leaves of plants and the mechanism of movement of plant juices. Later, because of poor vision Bonn was forced to leave the class natural history. He has published several philosophical works, which bore a clear imprint of the ideas of Leibniz and Christian metaphysics. In the book of essays psychology (Essai de psychologie, 1754) and analysis capabilities of the soul (Essai analytique sur les facult s de l `me, 1760) Bonn argued that all mental activity is determined by physiological factors, which led to accusations of his fatalism and materialism. In the Discourse on organized bodies (Consid rations sur les corps organis s, 1762) he described the theory of epigenesis and presentation of pre-existence of nuclei, or "souls". The work contemplation of nature (Contemplation dela nature, 1764-1765) defended the principle of "natural continuity", which, in accordance with the traditions of the 18th century., Was presented to him as a grand staircase of living beings. These ideas, supplemented by the principle of "indestructibility of organisms", were developed in the Philosophical palingenesis (Paling n sie philosophique, 1769-1770). Bonn has had a significant influence on the philosophical thought of his time and was actually the forerunner of Psychophysiology. He died in Bonn Zhentode near Geneva, 20 May 1793.
