" I will not take advantage of the Philosophy of this; for, I suppose his meaning to be, that it is Natural to the Understanding to Receive a Light that is infused into it, as for the Eye to see by an Extraneous light; that is, it is an Organ fitted to Receive Light, tho' it has none in it self; as the Understanding to Apprehend, tho' it has no Reason or Light in it self."
— Leslie, Charles (1650-1722)
It is Written, 1 John. 3. 20. If our Heart Condemn us, God is greater than our heart, and knoweth all things. Now, by Heart, here must be meant the Natural light; because, if it means the Light which is God, God is not Greater than Himself. And it is supposed here that the Heart does not Know all Things: Therefore this must be meant of our Natural Conscience, and not of God. And now here is a Natural light, which does Reprove of Evil, which Mr. Penn supposes cannot be shewn, p. 30. Our Saviour says, Luk. xii. 57. Yea, and why even of your selves judge not what is Right? But why of your selves, if we have no Light at all of our selves whereby to Judge?
