Seeing several of these paintings [his series paintings 'Hommage to the square', Josef Albers painted in 1963-64] next to each other makes it obvious… - Josef Albers

For me, abstraction is real, probably more real than nature. I'll go further and say that abstraction is nearer my heart. I prefer to see with closed eyes.

And I learned very early [Josef Albers was then ten years old] how to make imitation of wood grain. This is something I have in common with Georges Braque. Braque also learned very early from his father how to imitate marble or wood grain. So I could easily make the appearance of oak or walnut on pine. That is very easy; a very simple technique. And I learned how to imitate marble. I never made such a good joke as Braque did. When he was in the Mediterranean he fooled his friends. He painted a rowboat that had wood on one side and marble on the other side. You see, when he'd row out of the city it looked as if he were in a boat of a different material than when he came back, you see, one side was imitation wood and the other side was imitation marble.

That question is so big that there is no end [Albers refers here to the relationship between colors and the source of light]. You see, they have just you cannot participate with it if you have not lubricated your eyes very thoroughly to see the little changes produced in our eye that has another action than any optical apparatus like photography. We must know that we have two ways of seeing. For instance, when we are indoors another part of the retina is engaged compared with when we are outdoors. If we are in warm light or cool light, in higher light or lower light.
