There is such a complete freedom now-a-days in respect to technique that I am rather inclined to disregard form so long as I am free and can express myself freely. I don't know of anything, respecting form, that makes much difference. The essential thing in form is to be free in whatever form is used. A free form does not assure freedom. As a form, it is just one more form. So that it comes to this, I suppose, that I believe in freedom regardless of form.
