out of that he should create fair thoughts; and soon he will of himself perceive that the beauty of one form is akin to the beauty of another, and that beauty in every form is one and the same. My view of what Plato is saying is that he is emphasizing that beauty can be seen in all things and that beauty is universal and the same.
Friedrich Nietzsche expresses For art to exist, for any sort of aesthetic activity to exist, a certain physiological precondition is indispensable: intoxication. I believe Nietzsche means that art can be a source of new values that create a beautiful illusion or joy and celebration which overrides some of the realities of life, like pain, suffering and uncertainty.
John Ruskin presents a more emotional view I have already noticed the example of very pure and high typical beauty which is to be found in the lines and gradations of unsullied snow: if, passing to the edge of a sheet of it, upon the Lower Alps, early in May, we find, as we are nearly sure to find, two or three little round openings pierced in it, and through these emergent, a slender, pensive, fragile flower, whose small, dark purple, fringed bell hangs down and shudders over the icy cleft that it has cloven, as if partly wondering at its own recent grave, and partly dying of very fatigue after its hard-won victory; we shall be, or we ought to be, moved by a totally different impression of loveliness from that which we receive among the dead ice and the idle clouds. There is now uttered to us a call for sympathy, now offered to us an image of moral purpose and achievement, which, however unconscious or senseless the creature may indeed be that so seems to call, cannot be heard without affection, nor contemplated without worship, by any of us whose heart is rightly tuned, or whose mind is clearly and surely sighted. Ruskin had strong religious beliefs and these are evident in his views. His belief was theocentric, that the beauty that nature and God had created provided a spiritual connection to beauty.
