 Schopenhauer donated his estate to help disabled Prussian soldiers and the families of those soldiers killed, who had participated in the suppression of the 1848 revolution. An assortment of photographs of Schopenhauer was taken during his final years, and although they reveal to us an old man, we should appreciate that Schopenhauer completed his main work, The World as Will and Representation, by the time he had reached the age of thirty.
