Surounded by practical infinities

From the Neoproterozoic Era

I awaked each morning in a fever, sometimes frantically trying to verify or discredit such information as fell within the range of modern human knowledge. Traditional facts took on new and doubtful aspects, and I marvelled at the dream-fancy which could invent such surprising addenda to history and science. I shivered at the mysteries the past may conceal, and trembled at the menaces the future may bring forth. What was hinted in the speech of post-human entities of the fate of mankind produced such an effect on me that I will not set it down here.
