Whatever is fitted in any sort to excite the ideas of pain and danger, that is to say, whatever is in any sort terrible, or is conversant about terrible objects, or operates in a manner analogous to terror, is a source of the sublime; that is, it is productive of the strongest emotion which the mind is capable of feeling... When danger or pain press too nearly, they are incapable of giving any delight, and are simply terrible; but at certain distances, and with certain modifications, they may be, and they are, delightful, as we every day experience.
Edmund BurkeAdversity is a severe instructor, set over us by one who knows us better than we do ourselves, as he loves us better too. He that wrestles with us strengthens our nerves and sharpens our skill. Our antagonist is our helper. This conflict with difficulty makes us acquainted with our object, and compels us to consider it in all its relations. It will not suffer us to be superficial.
Edmund BurkeThe science of constructing a commonwealth, or renovating it, or reforming it, is, like every other experimental science, not to be taught a priori. Nor is it a short experience that can instruct us in that practical science, because the real effects of moral causes are not always immediate.
