Answer:
“point out the way” to “higher eminences of thought.”
inject “genius, mental vigour, and moral courage” into a conforming public.
Step-by-step explanation:
These are the two reasons why John Stuart Mill believes that exceptional individuals can be valuable to a culture. Mill was a defendant of freedom of speech, as he believed this was the only way in which new ideas can arise and spread in a society. Moreover, Mill believed that individuals who were exceptional would spread these new ideas and therefore, inject society with mental strength, genius and moral courage, all of which would lead the society to a higher level of thought.
