Final answer:
Thomas Jefferson is the one who said that the ultimate powers of society should rest with the people and that education is the key to an informed electorate capable of wise governance.
Step-by-step explanation:
The quote "I know no safe depository of the ultimate powers of the society but the people themselves, and if we think them not enlightened enough to exercise their control with a wholesome discretion, the remedy is not to take it from them but to inform their discretion" was said by Thomas Jefferson. Jefferson was an advocate for democracy and the belief that an informed citizenry is a critical component of a functioning republic. This quote emphasizes his stance that power should rest with the people, and if the people's ability to make informed decisions is lacking, the solution is to educate them, not to strip away their power.
