Context

“scattered along the page, to come at the profitable level of what he has to say. What he calls his religion is for the most part offensive to the nostrils. He should know better than expose himself, and keep his foul sores covered till they are quite healed. There is more religion in men’s science than there is science in their religion. Let us make haste to the report of the committee on swine. A man’s real faith is never contained in his creed, nor is his creed an article of his faith. The last is never adopted. This it is that permits him to smile ever, and to live even as bravely as he does.” source
