Feynman did physics and told stories.

He was very serious about his physics and wrote that stuff down.

Someone else wrote down his stories. His stories were probably often not entirely accurate, and whomever wrote down his stories also probably had an agenda. So books "by feynman" should be treated with some caution since they're written not by feynman.

His physics and science are obviously not "a sham". It is in fact possible for someone to be great and awful at the same time.
