It is He who gave to this intellectual nature free-will of such a kind, that if he wishes to forsake God his blessedness, misery should forthwith result.
In a discussion of this kind our interest should be centered not on the weight of the authority but on the weight of the argument. Indeed the authority of those who set out to teach is often an impediment to those who wish to learn. They cease to use their own judgment and regard as gospel whatever is put forward by their chosen teacher.
Nature doesn't ask your permission; it doesn't care about your wishes, or whether you like its laws or not. You're obliged to accept it as it is, and consequently all its results as well.
