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.
And yet I have had the weakness, and have still the weakness, to wish you to know with what a sudden mastery you kindled me, heap of ashes that I am, into fire.
My weaknesses... I wish I could come up with something. I'd probably have the same pause if you asked me what my strengths are. Maybe they're the same thing.
