Do ask yourself why you, the individual, exist, and if you can get no other answer try for once to justify the meaning of your existence as it were a posteriori by setting before yourself an aim, a goal, a 'to this end', an exalted and noble 'to this end'.
Friedrich NietzscheMetaphysical world.- It is true, there could be a metaphysical world; the absolute possibility of it is hardly to be disputed. We behold all things through the human head and cannot cut off this head; while the question nonetheless remains what of the world would still be there if one had cut it off.
Friedrich Nietzsche
