Answer:
a stoic
Step-by-step explanation:
The Stoics were thinkers who believed that human capacities were linked to a cosmic, hemodynamic and divine force, even the ability to reason and work. These thinkers do not believe that material goods, friendships, and health were not essential, but secondary. The essential thing was to cultivate the good, to be in contact with nature and to have a good reputation.
For this reason, we can say that the phrase "I believe we all have a spark of godly intelligence, that we must live in agreement with nature, and that we must develop good character" could be said by a stoic.
