“ THE simplest forms of insanity are those which consist merely of false perceptions, and they are not of such a character as to lessen the responsibility of the individual. There are two forms of false perceptions—illusions and hallucinations. Uncomplicated illusions are rare; still there is no doubt that there are illusions not the results of disease in the organs of sense or of circumstances unfavorable to exact perception, but which are due to a morbid condition of the perceptional ganglia, and the unreal nature of which is clearly recognized by the individual. ”

“ What then is there left of the Organon to find in these psychological dialogues? It is true that in these dialogues definition, the concept, etc., are noticed, but is this not much like saying that the doctrine of evolution is only Anaximander's "slime" done over again? The attempts to identify the philosophies of Plato and Aristotle from Ammonios Sakkas on, have never met with much success, in the face of which the statement that the very Organon is "little more than an abstract," etc., is rather strong. ”

“ If there is no organ of sense, there can be no normal sensorial impression; if the optic nerve be divided, the sensation can not be transmitted to the optic thalamus; if there be a diseased optic thalamus, the sensorial impression will be perverted and there will be an illusion of centric origin; if the cortex be in a normal condition, this illusion will be corrected and understood as such erroneous perception; if, however, the cortex be diseased, the illusion will be accepted as true, and a false idea, or delusion, will be formed. ”
