When G.E. Moore, in his Principia Ethica, argues for the existence of Beauty he gives us a pragmatic conclusion for its existence. He writes:
If it be once admitted that the beautiful world in itself is better than the ugly, then it follows, that however many beings may enjoy it, and however much better their enjoyment may be than it is itself, yet its mere existence adds something to the goodness o the whole: it is not only a means to our ends, but also itself a part thereof. (Principia Ethica pg. 137)
