Neutral-inclusive thought is characterized by three critical steps. When taking the neutralist starting point (rather than the relevantist one, as we have done in the Book of Fundamentals), the first step is that of assigning the highest normative value to the neutral predicate, and lower values to unneutral predicates. The second step is the realization that there are two sides to the neutral ideal: neutrality proper and the striving for neutrality, which is not neutral in itself. And the third step is the recognition of the inseparability of neutral and inclusive thought. It is on the grounds of this model that every symbol which is, strictly speaking, only neutralistic does represent the ideal of inclusivity as well.

The distinction between neutrality proper and the striving for neutrality corresponds to the distinction between an original catena and its neutral-directedness catena. While neutrality proper (ananicity) is the central predicate of an original catena, the striving for this neutrality is the positivity of the neutral-directedness catena of such an original catena. (Its neutrality is nan-neutral-directedness, and its negativity un-neutral-directedness.) This neutral-directed (nanapolar) striving is purely directional and can therefore be represented by an arrow. In a one-dimensional space in which neutralness is represented by a point, the striving for neutralness has two directions: one from the one extreme to the center, and the other from the opposite extreme to the center. Since the catena is analogous to a one-dimensional space (that is, a line), a line with a distinct point in the center can be considered representing a catena (of which the neutrality corresponds to the distinct point). The positivity of the neutral-directedness or nanaicity catena can be superimposed on this image of the original catena by adding an arrow which represents the striving for neutrality thru positivity (increase) and an arrow which represents the striving for neutrality thru negativity (decrease). The two arrows will meet in the one point representing the neutrality of the original catena. The central sign which emerges in this figure looks like a multiplication sign (X), and the image has now become two-dimensional. Altho the total figure consisting of the straight line and the central sign ( ---X--- ) is still rather primitive, it does already symbolize both aspects of neutral thought, namely the recognition of the special status of (ananormative) neutrality and the significance of all (ananormative) striving for neutrality.

The simple figure formed by two arrows meeting in the middle is a visual and/or tactual symbol of neutrality, nanapolarity and the positivity and negativity of the original catena thru which neutrality can be achieved. It represents the whole basic or other original catena and the nanapolar predicate related to this catena. We shall call this concrete symbol "the (Nanapolarity) Catena" or "nanacatena" for short. (Since the symbol itself, or a concrete object, is not a catena, (Nanapolarity) Catena is a name to be capitalized.) Where the nanacatena is present, this is a nonfundamental sign of the belief in ananicity and nanaicity. (Nonfundamental in that it cannot be compared to the two fundamental symbols of the DNI.) The nanacatena is not the symbol of a nanaicity or neutral-directedness catena, because such a symbol would not only represent neutral-directedness but also nan- and un-neutral-directedness.

The center of the Nanapolarity Catena symbolizes neutrality; the left of it positivity --the further to the left the more positive-- and the right negativity --the further to the right the more negative--, or vice versa. To indicate the degree of negativeness and positiveness we can make the 'line' thicker and thicker as we move from the neutral point. The degree of unneutralness is now also visualized or tactualized (that is, made tactual or tangible). Negative unneutrality and positive unneutrality must not be differentiated in a nanacatena, for they have exactly the same value according to the ananorm. Suffice it that one is on the sinister, the other on the dexter side of the center.

The original left and right lines which have become surfaces may be bordered by a straight line or by a (part of a) curve such as a circle. When these surfaces are bordered by straight lines, the nanacatena consists of two equicrural, but not equilateral, triangles of which the top angles meet in a point marked by the central sign of the nanacatena (the X sign which emerges when an arrow is mirrored). The central sign can only stand out when the base of the identical triangles is made considerably shorter than the sides. Also when the surfaces are bordered by curves, or parts of curves, this central sign has to show clearly. The surfaces themselves (representing the unneutralities) may be either filled in or left blank. When filled in the variant of the nanacatena may be called "solid", when left blank "open". Figure S.4.1.1.1 shows a number of open and solid variants of the nanacatena, and one intermediate, dashed variant. If the surfaces are not achromatic (white, grey and/or black), they should represent all colors of a spectrum with (yellowish) green as the central color at either side of the sign of neutrality.

Every variant of the Nanapolarity Catena must comply with the basic rules for this figure in order to be recognizable as a symbol of neutralism, and therefore also of inclusivism. For people who have the power of sight the Catena may represent the DNI in a visible way by displaying it on a piece of paper or fabric, for instance; for people who have a sense of touch the Catena may represent the DNI in a tangible way, such as by means of a sculpture or a carving in relief. It is not necessary to present one, technically and esthetically entirely worked-out, final shape of the nanacatena. Within the frame given here several possibilities remain. What is important is that the Nanapolarity Catena is --irrespective of individual variations-- truly symbolic of the quintessence of the DNI.
