passages from Wassily Kandinsky's "Line and Fish" (1935)

Approaching it in one way I see no essential difference between a line one calls "abstract" and a fish.

But an essential likeness.

This isolated line and the isolated fish are living beings with forces peculiar to them, though latent. They are forces of expression for these beings and of impression on human beings. Because each being has an impressive "look" which manifests itself by its expression.
