I make known the end from the beginning, from ancient times, what is still to come. I say, ‘My purpose will stand, and I will do all that I please.’ ~Isaiah 46:10 In The Republic, Socrates repeatedly insists that truth will be the highest value of his utopian society. To accomplish this, he argues that the myths of Homer and Hesiod should be hewn down to only those stories that are in accordance with what we know to be true, by proper philosophic study and dialectic argumentation.
Hume infers from his insight that it is not reason but moral opinion that moves us to act, that reason is not the source of moral opinion. From this, he then further argues that moral opinion is a product of the passions – special emotions that arise out of the relations of ideas and impressions. In this essay, I will argue that Hume’s initial inference is correct, but that his subsequent inference is not.
