Universal Natural History and Theory of the Heavens
|Original title||Allgemeine Naturgeschichte und Theorie des Himmels|
Universal Natural History and Theory of the Heavens (German: Allgemeine Naturgeschichte und Theorie des Himmels), subtitled or an Attempt to Account for the Constitutional and Mechanical Origin of the Universe upon Newtonian Principles,[a] is a work written and published anonymously by Immanuel Kant in 1755.
According to Kant, the Solar System is merely a smaller version of the fixed star systems, such as the Milky Way and other galaxies. The cosmogony that Kant proposes is closer to today's accepted ideas than that of some of his contemporary thinkers such as Pierre-Simon Laplace. Moreover, Kant's thought in this volume is strongly influenced by atomist theory, in addition to the ideas of Lucretius.
Kant won the Berlin Academy Prize in 1754 for his argument that the Moon's gravity would eventually cause its tidal locking to coincide with the Earth's rotation. The next year, he expanded this reasoning to the formation and evolution of the Solar System in the Universal Natural History.
Within the work Kant quotes Pierre Louis Maupertuis, who discusses six bright celestial objects listed by Edmond Halley, including Andromeda. Most of these are nebulae, but Maupertuis notes that about one-fourth of them are collections of stars—accompanied by white glows which they would be unable to cause on their own. Halley points to light created before the birth of the Sun, while William Derham "compares them to openings through which shines another immeasurable region and perhaps the fire of heaven." He also observed that the collections of stars were much more distant than stars observed around them. Johannes Hevelius noted that the bright spots were massive and were flattened by a rotating motion; they are in fact galaxies.
Kant's book ends with an almost mystical expression of appreciation for nature: "In the universal silence of nature and in the calm of the senses the immortal spirit’s hidden faculty of knowledge speaks an ineffable language and gives [us] undeveloped concepts, which are indeed felt, but do not let themselves be described."
In his introduction to the English translation of Kant's book, Stanley Jaki criticises Kant for being a poor mathematician and downplays the relevance of his contribution to science. However, such criticisms are on the whole unfair, as they are blaming Kant for not knowing about 20th-century developments.
