"Climbing the last light..."*

*"Look! Look! he is climbing the last light Who knows neither Time nor error, and under Whose eye, unforgiving, the world, unforgiven, swings Into shadow." –from "Evening Hawk" by Robert Penn Warren

"To me, the universe is simply a great machine which never came into being and never will end. The human being is no exception to the natural order. Man, like the universe, is a machine. Nothing enters our minds or determines our actions which is not directly or indirectly a response to stimuli beating upon our sense organs from without.” -Nikola Tesla.
