Form: Like the notion "room" for a real architects, to a designer "form" becomes increasingly mysterious the more one knows about it. According to Aristotle’s Metaphysics, form is what you get when you put energy into matter. Form is the key quality that turns shapeless matter into "the thing it is." Form takes shape in our mind through thought. In physical reality, there are no perfect triangles and circles, no perfectly identical ones that add up to a perfect two. In our mind perfect triangles, circles, lines and numbers exist in crystal clarity. As if that wasn't confusing enough, it seems that it's form (essentially a mental process) and not matter that makes things real. (Quantum physics kind of agrees there, but that doesn't make it simpler or more down to earth, and Aristotle knew 2,350 years before Heisenberg.) Matter is shapeless stuff that—in its shapeless form—doesn't matter much to us—until it takes shape. Thinking is the endeavor to build shapeless sensation or emotion into form. So, to begin with form is thought. Expressing or producing that form makes sensation transmittable, thinking, making sense is giving sensation a transmittable form. Communication is the complex process of turning more or less shapeless sensation into intelligible form (which we call thought when used internally, language when used symbolically with others), and back. We express impressions through language using standardized symbols.
