But so long as the nineteenth century remains “still the most obscure of all the centuries of the modern age up to now” (Heidegger, 1977, pp. 139–140), even the true significance of our present endeavors may remain yet unknown and unknowable to us. The only alternative is blank incomprehension, the sort already possible within about fifty years of his death; for when Wittgenstein’s student Drury complained about the inclusion of Lotze as a special author in the second part of his Tripos, Wittgenstein could only reply: “Probably a man who shouldn’t have been allowed to write philosophy” (Rhees, 1981, p. 121).
