From the sentence:
Grave, taking life at its own face value and a little too seriously, with a deportment as unbending as it is "correct" , he is yet the least formidable of men.
Some people interpret "he is yet the least formidable of men" as he is not formidable at all in the crowd. But seems that the "yet" means "still" would be more natural. So what is the meaning of it? Is it different from "he is the least formidable yet "?
