Jonathan swift a. hated individual men but loved powerful groups b. feared both individual men and powerful groups c. feared powerful political groups but believed that individual men can be reasonable and responsible d. believed that all men are as reasonable as houyhnhnms

The correct answer is C. feared powerful political groups but believed that individual men can be reasonable and responsible.
Swift was against various political organizations because he believed they were corrupted and they tried to corrupt individuals as well. He believed that people themselves weren't bad, it's just when given power and a chance to control others, they would eventually turn corrupt. His thought was that individuals could also be powerful, whilst retaining their senses, which he did not think was possible in groups.
