The more earnestly you go into the thing, the closelier you look, the more the picture is lost in reticulations. I submit, the world

If you push a philosophical or metaphysical inquiry through a series of valid syllogisms - never committing any generally recognised fallacy - you nevertheless leave behind you at each step a certain rubbing and marginal loss of objective truth, and you get deflections that are difficult to trace at each phase in the process.
