I am happy to report that the sources of the Tennyson and Saint-Simon references have been identified. I have had 2 references for Kant, though neither one using the exact phrase in English that Hayek used. This is interesting because I have seen the same English phrase used elsewhere. I still have had no takers on the Comte and Disraeli phrases and would be happy to receive any help with them - and I did google them both, but to no avail. Again, thanks to those who took the time and effort to reply. Bruce Caldwell
