What determines the will?

Jonathan Edwards, "With respect to that grand inquiry, 'What determines the Will? it would be very tedious and unnecessary, at present, to examine all the various opinions, which have been advanced concerning this matter; nor is it needful that I should enter into a particular discussion of all points debated in disputes on that other question, 'Whether the will always follows the last dictate of the understanding?' It is sufficient to my present purpose to say, It is that motive, which, as it stands in view of the mind, is the strongest, that determines the Will." Freedom of the Will, Pg. 9


This reminds me of what Gordon Clark says in Religion, Revelation and Reason

Clark says, "The primacy of the intellect, then, cannot be a power automatically exercised over the volition regarded as a separate faculty. This would violate the unity of the person. Instead of the phrase 'THE PRIMACY OF THE INTELLECT', the essential idea might better be expressed as 'THE PRIMACY OF THE TRUTH'. And the primacy is one of authority rather than of psychological power. The older forms of expression generate an old perplexity dating from Platonic dialogues. On the assumption that the intellect dominates the will, it would follow that no one does wrong knowingly. All evil is due to ignorance, and education guarantees correct conduct. The ambiguities hidden in this apparently simple language are enormous. But if we speak of the primacy of truth, we can avoid, even if we do not solve, these perplexities. The primacy of truth will mean that our voluntary actions ought to conform to the truth. Obviously sometimes they do not. If it is true that worshiping God is good, we ought to worship him. Perhaps we choose not to worship God, but the truth is superior in right to our will. This way of putting the matter extends as well to the voluntary choice of belief. We may choose to believe a truth, or we may choose to believe a lie. Both types of choice actually occur. But the primacy of truth means that we ought to believe the truth and we ought not to believe the lie." - Emphasis is mine. Found in his Three R's
