<human>:  Why did Charles Darwin not want to be a naturalist?
<bot>: Charles Darwin did not want to be a naturalist because he wanted to be a gentleman. A gentleman is someone who is educated and well-mannered, and who is well-liked by other people. A gentleman is someone who is not afraid to admit when they are wrong. Darwin was afraid to admit that he was wrong about his theory of evolution, so he chose not to be a naturalist.
