Collier's views on religion and ethics are interesting for their comparison with the views of Thomas Henry Huxley and Julian Huxley, both of whom gave Romanes lectures on that subject. In "The religion of an artist" (1926) Collier explains "It book is mostly concerned with ethics apart from religion... I am looking forward to a time when ethics will have taken the place of religion... My religion is really negative. benefits of religion can be attained by other means which are less conducive to strife and which put less strain on upon the reasoning faculties". On secular morality: "My standard is frankly utilitarian. As far as morality is intuitive, I think it may be reduced to an inherent impulse of kindliness towards our fellow citizens". On the idea of God: "People may claim without much exaggeration that the belief in God is universal. They omit to add that superstition, often of the most degraded kind, is just as universal". And "An omnipotent Deity who sentences even the vilest of his creatures to eternal torture is infinitely more cruel than the cruellest man". And on the Church: "To me, as to most Englishmen, the triumph of Roman Catholicism would mean an unspeakable disaster to the cause of civilization". His views, then, were very close to the agnosticism of Thomas Henry Huxley and the humanism of Julian Huxley.
