Some people may therefore effectively design themselves in whilst others design themselves out. Parts of some people may be in, whilst other parts are out. How much of such a pattern is recognized by others will depend on the degrees of mutual reinforcement and fruitful challenge. Diversity may be understood as a range or set of functions vital to the viability of the pattern of coherence. But it is quite possible to have certain kinds of music omitting many octaves, chords or notes.
Viable ecosystems can function without many species.
How much diversity is therefore a question in endeavouring to understand the kind of unity or coherence that is individually sought. This may be a personal challenge to growing understanding. But in any pattern of diversity there needs to be some kind of coherence to the functions present. What those functions are and how they are distinguished is a challenge for the individual pattern-maker playing with the group environment. The energy of the collective enterprise will increase as each distinguishes more essential functions and develops a richer patterning for them.
