Tribalism
Imagine a family unit or a group of friends, and the variously helpful and malicious actions between them. Why do they remain in each other's lives?
Generally, we say that people make friends and keep them, or stay active within their family structure, because they feel close to these people and want to live alongside them. We say that this means augmenting the efforts of those they care about whilst minimising their risks and losses. We state this quite naturally, but we forget that on the ground this just doesn't look right.
Psychologically, the principle of common advantage doesn't enter the awareness of people when they have to make any one of the vast number of petty decisions that make up their everyday lives. It doesn't happen that whenever someone picks up a newspaper for someone else, they really consider why they do so. Reason doesn't really seem to have an input. We'd want to say, however, that although everyday action isn't derived from rational principles, it is nonetheless true that altruism is the determining factor. Again, I say this doesn't look right.
While it's probably true that people have in the main no conscious knowledge of the grounds of their relationships, this doesn't mean that tribalism (call it whatever) is a good thing rather than a bad thing. The way that an individual behaves within a network of people they are close with is often predatory. Mood swings are sent rippling out, having a negative impact upon others, and yet this isn't an arbitrary action - real positions of power and dominance are effected in this way. Indeed, we all know groups of people who constantly abuse and vie for position over each other. We know also that most friendships are borne solely out of the desire to feel better about oneself, without any thought for those people thereby befriended.
Victimisation seems a large part of tribal behaviour, and is perhaps directly proportional to the stupidity of the people bound into the tribe. This is particularly striking when we become momentarily assimilated into a tribal community, and a pecking order asserts itself roughly upon us, manifesting itself in our reactions to the feelings aroused by the abusive behaviour. Let us assume that people remain in these relationships through stupidity (though what exactly this means we'd have to do work on): What do we do when we are caught up in a tribal drama?
Patience and tolerance are key of course. Yet insofar as we are already caught up in a tribal drama, we are being buffetted around - we are ourselves reacting, rather than acting virtuously. Retrospectively, however, we can identify patience and tolerance as desirable, in the sense that it is good to act patiently and tolerantly in an abusive tribal situation. But we know that these are lesser goods - that it is better to avoid these situations in the first place (where we don't know that we have the strength to deal with them).
To help inform this issue, see Spinoza's Ethics, Part IV, Propositions 69-71. The Curley translation states these as:
P69: The virtue of a free man is seen to be as great in avoiding dangers as in overcoming them.
P70: A free man who lives among the ignorant strives, as far as he can, to avoid their favors.
P71: Only free men are very thankful to one another.
This last proposition is the one that elucidates the status of the tribal community. Insofar as people know why they network with each other, and act according to reason and virtue to secure their common advantage, this is a true community, and those within it are noble. But of the tribal community, the Scholium to P71 states in part:
"The thankfulness which men are led by blind desire to display toward one another is for the most part a business transaction or an entrapment, rather than thankfulness." (Penguin,1994)
