2) Found: All four of the main readings (Schumacher, Lewis, Percy, Pinckaers) offer solutions to the problems they diagnose in the human condition. Given your summary diagnosis to the condition of human lostness in question 1 above, do one of the following: Option A, B or C: Chart a course correction to lostness by using all the main authors to explain a unified solution to the condition of personal (and thus social) lostness; or if not a solution, because the human condition is insoluble, what resources do the authors we have read recommend for orienting ourselves in the Cosmos?  Option D. What do you prescribe to bring health to a professor (or indeed, his other students) whose sickness may not yet be unto death?
