"Van Gogh's work had hitherto been very dark, with scarcely any color, and he was at first bewildered by the rich coloring and the light which he discovered in the impressionist pictures. But when Pissarro explained to him the theory and technique of his own paintings, van Gogh began to experiment and immediately took to the new ideas with great enthusiasm. He completely changed his palette and his execution, even adopting for a while the neo-impressionist dot, although he used it without systematic."

“..Here I am shut up for the livelong day under lock and key and with keepers in a cell.. ..I will not deny that I would rather have died than have caused and suffered such trouble.”

“And my intention is to try to form a collection of many such things, which would not be quite unworthy of the title 'heads of the people.' By working hard, boy, I hope to succeed in making something good. It isn't there yet, but I aim at it, and struggle for it. I want something serious, - some thing fresh - something with soul in it! Forward - forward”

“My dear Theo, Feeling, even a fine feeling, for the beauties of nature isn't the same as religious feeling, although I believe that the two are closely connected. The same is true of a feeling for art. Don't give in to that too much either. Hold fast especially to your love for the firm and for your work.. ..Nearly everyone has a feeling for nature, some more than others, but there are few who feel that God is a spirit, and that they must worship Him in spirit and in truth. Pa is one of the few, Ma too, and also Uncle Vincent, I believe.”

“If only we try to live sincerely, it will go well with us, even though we are certain to experience real sorrow, and great disappointments, and also will probably commit great faults and do wrong things, but it certainly is true, that it is better to be high-spirited, even though one makes more mistakes, than to be narrow-minded and all too prudent. It is good to love many things, for therein lies the true strength, and whosoever loves much performs much, and can accomplish much, and what is done in love, is well done.”
