Art is the pure realization ...

Art is the pure realization of religious feeling, capacity for faith, longing for God. ... The ability to believe is our outstanding quality, and only art adequately translates it into reality. But when we assuage our need for faith with an ideology we court disaster.
 Gerhard Richter

Quotes from the same author

And then the work bears a strong sense of leave-taking for me personally. It ends the work I began in the 1960s (paintings from black-and-white photographs), with a compressed summation that precludes any possible continuation. And so it is a leave-taking from thoughts and feelings of my own on a very basic level. Not that this is a deliberate act, of course; it is a quasi-automatic sequence of disintegration and reformation which I can perceive, as always, only in retrospect.
 Gerhard Richter
Painting is consequently an almost blind, desperate effort, like that of a person abandoned, helpless, in totally incomprehensible surroundings.
 Gerhard Richter
I have no motif, only motivation. I believe that motivation is the real thing, the natural thing, and that the motif is old-fashioned, even reactionary (as stupid as the question about the meaning of life)
 Gerhard Richter
If, while I'm painting, I distort or destroy a motif, it is not a planned or conscious act, but rather it has a different justification: I see the motif, the way I painted it, is somehow ugly or unbearable. Then I try to follow my feelings and make it attractive. And that means a process of painting, changing or destroying - for however long it takes - until I think it has improved. And I don't demand an explanation from myself as to why this is so.
 Gerhard Richter
I don't know what motivated the artist, which means that the paintings have an intrinsic quality. I think Goethe called it the 'essential dimension,' the thing that makes great works of art great.
