I must stay alone and know that I am alone to contemplate and feel nature in full.
Caspar David FriedrichA painting which does not take its inspiration from the heart is nothing more than futile juggling.
Caspar David FriedrichThe artist should paint not only what he sees before him, but also what he sees within him. If, however, he sees nothing within him, then he should also refrain from painting that which he sees before him. Otherwise, his pictures will be like those folding screens behind which one expects to find only the sick or the dead.
