Diego Rivera said this quote

An artist is above all a human being, profoundly human to the core. If the artist can’t feel everything that humanity feels, if the artist isn’tcapable of loving until he forgets himself and sacrifices himself if necessary, if he won’t put down his magic brush and head the fightagainst the oppressor, then he isn’t a great artist.

~ Diego Rivera

I knew how one climbing the mountain of worldly success can slip down into the river below without being conscious of the descent till he is already drowning.

From sunrise to sunset, I was in the forest, sometimes far from the house, with my goat who watched me as a mother does a child. All the animals in the forest became my friends, even dangerous and poisonous ones. Thanks to my goat-mother and my Indian nurse, I have always enjoyed the trust of animals--a precious gift. I still love animals infinitely more than human beings.

~ Diego Rivera

I am an atheist and I consider religions to be a form of collective neurosis. I am not an enemy of the Catholics, as I am not an enemy of the tuberculars, the myopic or the paralytics; you cannot be an enemy of the sick, only their good friend in order to help them cure themselves.
