"Actually I don't have any painting at home.. ..they take away everything from me, almost before it's finished.. .That Jewish scribe there, is sold to Buffa, and it isn't finished at all yet. And this 'Kolen lossen' is also sold.. .Then I have here 'The Mowers' - just set up.. .And that drawing here, will be a good piece too!. .That will become a large painting: a 'Jewish Wedding' - at the moment the groom puts the ring on the finger of his bride.. ..you can't see very much yet, do you?"

“That is always difficult and can only become a potboiler.”

“..the owner .. ..had to hear a lot of comments about it, they called it the apotheosis of a cape, the figure much too big for the frame, etc. etc. so they advised him to exchange it for one of my other works.”

“Take care for purity in the paint and not so stinky thick of grease, thin, thin, thin!

“..on my travels, for example, abroad,. .I see things that attract me, in the works of others, - which impress me. That's what you reflect upon at times. And when you come home you think: Me too have to make something like that.. .Then you start, and when it's finished it looks like the work of that person or another.. .But your own originality doesn't get lost, - your sentiment remains!. .And this happens not only to me, - this happens to others also.. .Unintentionally you continue to build on motives of others..”
