What do you think about art?

What do you think about art?
Or What is art for you?
Yestarday I came to Grenoble Museum & I discovered the "Hidden collection" of Gauguin.
Personnaly, I'm just disappointed because I discovered that Gauguin was married & that he was "in love" with another woman...
I adore Gauguin's work (oeuvre) but the fact that he was married & that he "loved" another woman disapointed me...
I hate men that are in this way of thinking.
But, I reflect myself & I realize that Gauguin (from that I know), never "cheat" his wife so I think that art could be an expression of ourselves & it can allow expression of what we have in our spirit.
I went to the "abstract section" & I discovered many "strange things" that I never saw before & I thank in myself : "They are crazy!!".
Yes, I think they are crazy.
But, are not we all crazy?
