What strange adventures await us in those yet untraveled regions toward which we speed? — into what malign conditions may we not at any time plunge? — to the strength and stress of what frightful environment may we not at last succumb? The subject lends itself readily enough to a jest, but I am not jesting: it is really altogether probable that our solar system, racing through space with inconceivable velocity, will one day enter a region charged with something deleterious to the human brain, minding us all mad-wise.

O God! what a thing it is to be a ghost, cowering and shivering in an altered world, a prey to apprehension and despair!

IMMORAL, adj. Inexpedient. Whatever in the long run and with regard to the greater number of instances men find to be generally inexpedient comes to be considered wrong, wicked, immoral. If man's notions of right and wrong have any other basis than this of expediency; if they originated, or could have originated, in any other way; if actions have in themselves a moral character apart from, and nowise dependent on, their consequences — then all philosophy is a lie and reason a disorder of the mind.
