We can't say that when the mind disobeys, it's like fire or air rising toward their natural place. The mind does the opposite. When the mind moves toward injustice, lack of self-control, sorrow, or fear, it's separating from its nature. When the mind grieves over what divine providence has brought about, it abandons its proper place. The mind was meant for holiness and reverence. These come from humble acceptance of God and his providence in all things. They come from justice too. These are duties we owe as social beings. Without them, we can't live peacefully together. They are the foundation of all right action.
For we cannot say of it when it is disobedient, as we say of the fire, or air, that it tends upwards towards its proper element, for then goes it the quite contrary way. For the motion of the mind to any injustice, or incontinency, or to sorrow, or to fear, is nothing else but a separation from nature. Also when the mind is grieved for anything that is happened by the divine providence, then doth it likewise forsake its own place. For it was ordained unto holiness and godliness, which specially consist in an humble submission to God and His providence in all things; as well as unto justice: these also being part of those duties, which as naturally sociable, we are bound unto; and without which we cannot happily converse one with another: yea and the very ground and fountain indeed of all just actions.
