Unlike some other reproductions of classic texts (1) We have not used OCR(Optical Character Recognition), as this leads to bad quality books with introduced typos. (2) In books where there are images such as portraits, maps, sketches etc We have endeavoured to keep the quality of these images, so they represent accurately the original artefact. Although occasionally there may be certain imperfections with these old texts, we feel they deserve to be made available for future generations to enjoy.

At a time when German philosophy was dominated by idealism, German philosopher and physician Ludwig Buchner (1824-99) wrote Kraft und Stoff, an influential work advocating materialism, in 1855. It went through many editions and was widely read across the world. The controversy surrounding the book led to Buchner leaving his post at the University of Tubingen, but he went on to establish the German Freethinkers' League, the first German organisation for atheists. This book, first published in 1864, is a translation of the eighth edition, and is edited by J. Frederick Collingwood, who wanted to bring Buchner's work to an English audience. It contains translations of the prefaces from the first, third and fourth editions of Kraft und Stoff, and an introductory letter from Buchner which expresses his belief that Darwin's theory of evolution has given support to his materialist theory.
