He published in 1910 The Prevention of Malaria, and also produced Psychologies, a volume of poems (1919), and a romance, The Revels of Orsera (1920).
Reason, as in most modern psychologies and idealisms, is introduced by Wundt, after all sorts of operations, too late; and, when at length introduced, it is described as going beyond ideas and notions to " ideals " (Ideen), as an ideall continuation of series of thoughts beyond given experience - nothing more.
In this account of the development of an independent, active and intelligent being from the stage where man like the Dryad is a portion of the natural life around him, Hegel has combined what may be termed a physiology and pathology of the mind - a subject far wider than that of ordinary psychologies, and one of vast intrinsic importance.
