Baarlam had already been condemned by St Thomas Aqvinas (among other things, First Part, First Question of the Summa Theologiae), and was further condemned by Pius IX of Rome, in the Syllabus errorum, witness following condemned propositions:
3. Human reason, without any reference whatsoever to God, is the sole arbiter of truth and falsehood, and of good and evil; it is law to itself, and suffices, by its natural force, to secure the welfare of men and of nations. -- Ibid.
4. All the truths of religion proceed from the innate strength of human reason; hence reason is the ultimate standard by which man can and ought to arrive at the knowledge of all truths of every kind. -- Ibid. and Encyclical "Qui pluribus," Nov. 9, 1846, etc.
