Treatise of Human Nature

Thus we have accounted for three phenomena, which seem pretty remarkable. Why distance weakens the conception and passion: Why distance in time has a greater effect than that in space: And why distance in past time has still a greater effect than that in future. We must now consider three phenomena, which seem to be, in a manner, the reverse of these: Why a very great distance encreases our esteem and admiration for an object: Why such a distance in time encreases it more than that in space: And a distance in past time more than that in future.
