[Footnote 2: Perhaps the story of the stones arose from the like sound of [Greek: Laos] and [Greek: Laas], words here regarded in the inverse relation to each other.]

The German positivists:E. Laas of Strasburg (1837-85), A. Riehl of Freiburg in Baden (born 1844), and R. Avenarius of Zurich (born 1843)develop their sensationalistic theory of knowledge in critical connection with Kant.

Ernst Laas defines positivism (founded by Protagoras, advocated in modern times by Hume and J.S. Mill, and hostile to Platonic idealism) as that philosophy which recognizes no other foundations than positive facts (i.e., perceptions), and requires every opinion to exhibit the experiences on which it rests.

The third volume of Laas's work differs from the earlier ones by conceding the rank of facts to the principles of logic as well as to perception.
