I cannot deny that if the loud report of an arquebus suddenly strikes on my ear in a place where I have no reason to expect it, I am startled; which I have seen happen to others more valorous than I.
—Montaigne (Essays, ‘On Steadfastness’)
Is steadfastness then to apply only in those circumstances that meet expectations? No, of course not. Yet strange how steadfastness is so similar to impassivity or inertia.
