I hope folks are not suggesting that Hayek "got" this from nowhere. My 
copy of Pearson's /Grammar of Science/ (3rd ed. 1911, printed in 
Austria) has its Chapter 2 concerned with just such 
experience-processing. And Bruce Caldwell has been showing how /Sensory 
Order/ grew from Kant as well as Hayek's own student paper.
