found: Wikipedia, Dec. 4, 2013:"Karl Christian Planck" (Karl Christian Planck; in 1850-1851, published his great book, Die Weltalter, in which he developed a complete original system of philosophy, based on the realist view that thought should proceed from nature to the highest forms of existence in the spiritual life; in so doing, he opposed the idealism of his contemporaries and at the same time the Darwinian theory of descent; the natural consequence of this individuality of opinion was that his books were practically disregarded and Planck was deeply incensed, his later works faring no better; after a short period of nervous prostration he died in an asylum)
