The introduction of a Distinction is first of all the introduction of a *form*.
A form is the distinction of an Inside (of the distinguished) from an Outside (of the thing). So the introduction of any distinction is itself a distinction.
As a form, the symbol of X marks the difference of two sides: X and non-X. [⇒ Binate]
X is, in the terminology of George Spencer Brown, the Inside of the form and non-X the Outside.
For the form to cross from one side to the other, the system takes Time – whether it moves something from the status of X to the status of non-X or vice versa.
In any case the form exists only as a Two-Sided Form and the one side not without the other. And in any case both designations, the positive and the negative, are results of internal operations of the system and are related to internal states.
As with all symbols, a diabolical counter-case runs along.

**Niklas Luhmann**: Here [see Prozessunterbrechungen ; R.B.], I think, language is not quite up to par with what should be said. We need to bring the language back into line with our Intentions. So I would answer yes and no. On the one hand, everything that can be seen or said takes place in the world, and they are always, in this sense, statements about the world. But just not about the unity of the world or about that which can never be left.
And also not about the Whole. In this sense the theory is directed against holographic approaches, as they are offered today in the style of the New Age; somehow a trace of the whole is to be found in everything individual, somehow every element is a part in which the whole is "inscribed". **The concept of form is explicitly set against such a Holographic New Age Mysticism.**

Class Form
A rectangular array of pixels, used for holding images. All pictures, including character images are Forms. The depth of a Form is how many bits are used to specify the color at each pixel. The actual bits are held in a Bitmap, whose internal structure is different at each depth. Class Color allows you to deal with colors without knowing how they are actually encoded inside a Bitmap. The supported depths (in bits) are 1, 2, 4, 8, 16, and 32. The number of actual colors at these depths are: 2, 4, 16, 256, 32768, and 16 million. Forms are indexed starting at 0 instead of 1; thus, the top-left pixel of a Form has coordinates 0@0. Forms are combined using BitBlt. See the comment in class BitBlt. Forms that repeat many times to fill a large destination are InfiniteForms. colorAt: x@y Returns the abstract Color at this location displayAt: x@y shows this form on the screen displayOn: aMedium at: x@y shows this form in a Window, a Form, or other DisplayMedium fillColor: aColor Set all the pixels to the color. edit launch an editor to change the bits of this form. pixelValueAt: x@y The encoded color. The encoding depends on the depth.
