While the wearing of clothes is one way of regulating one's microclimate, the use of buildings is another. But just as the function of clothes is not only protection from the weather, so the function of buildings is not either. Preferably clothes should not only be practical but also beautiful and, if appropriate, symbolic of what the wearer does or feels, or of what 'e wants those who see 'im to do or feel. Similarly, buildings should not only be practical and beautiful, but should also be symbolic of their so-called 'function'. This 'function' is then not necessarily a practical one such as providing shelter against the rain or the sun, but anything for which the building is or will be used. In the last chapter of this book we will come to call a building or structure to be used as a communal center for both fundamentalists and symbolists an anakentron or "kentron" for short. (Kentron is what the words centrum and center derive from; it is thus both etymologically and symbolically related to the centrality of the neutral predicate.) The design of an anakentron is not a fundamental issue, but if a kentronic structure is to symbolically reflect its function, the pattern or main form of such a structure should be determined by neutralistic (or neutral-inclusivistic) symbolism. There are good possibilities of incorporating the shape of the Catena, for instance, into symbolistic architectonic structures. (Terming them "symbolistic" or "symbolic" is not to say that they could not be used as centers of fundamentalistic neutralism.)

Figure S.4.2.3.1 is a presentation of two examples of nanacatenary architectonic structures. In these examples the effect of a complete Catena is achieved in two different ways: firstly, by the reflection of the longitudinal half of the Catena in water; and secondly, by the reflection of the cross-sectional half in a glass mirror. Given that the symbols of ananicity are not all the same as the symbols of nanaicity, these structures cannot only be used as whole anakentrons but also as so-called 'Halls of Nanaicity'. These Halls are to be regarded as separate kentronic structures or parts of kentronic structures dedicated to nanaic action and the symbols of corrective neutralism. (Chapter Six will give more details on kentrons and other kinds of centers.)

By purposefully being given a direction to the equator an anakentron or Hall of Nanaicity is turned into a concrete symbol of global neutral-directedness. Thus 'equatored' the seats in figure S.4.2.3.1.b, for instance, will be facing south in the Northern and north in the Southern Hemisphere. (Note that such a kentronic structure is not 'oriented' to the south, let alone to an ideologically aggrandized particular place on Earth, as temples and palaces in former times.) Where and when it does not suit local conditions to have the whole building or hall face the equator, it may suffice to give only the (main) facade or entrance that direction. On the equator itself two equal entrances opposite each other (one on the north and one on the south side) could be symbolic of the same neutral-directedness.

Some names for nanacatenary structures are very appropriate in the event that they are to be used as anakentrons, but not in the event that they are to be used as Halls of Nanaicity. (While the Book of Fundamentals prohibits any kind of onomastic exclusivism.) Thus, names which have harmony, oneness or wholeness in them are more suitable for anakentrons, whereas names with nanaic(ity) or (nana)polar(ity) in them are more suitable for Halls of Nanaicity. If the shape of the structure is also to have a bearing on its name, then names with reflection(al), mirror(ed) and symmetrical deserve special attention. Examples for a kentron which is nanacatenary in design are then Anakentron of Reflectional Harmony / Oneness / Wholeness or Anakentron of Symmetrical Harmony; examples for such a Hall of Nanaicity are Hall of Nanaic Reflection or Hall of Mirrored Polarity.
