Alas! What is man? Whether he be deprived of that light which is from on high, of whether he discard it, a frail and trembling creature; standing on time, that bleak and narrow isthmus between two eternities, he sees nothing but impenetrable darkness on the one hand, and doubt, distrust, and conjecture, still more perplexing, on the other. Most gladly would he take an observation, as to whence he has come, or whither he is going; alas, he has not the means: his telescope is too dim, his compass too wavering, his plummet too short.
