1 – the only rational reason to cooperate is because it is more rewarding than both non-cooperation AND predation.
2 – the only rational terms of cooperation that are more rewarding than non-cooperation and predation are those of reciprocity.
3 – Reciprocity is only possible because of truthful (fully informed), productive, warrantied, voluntary transfer, free of externality.
4 – The only grammars of truthful speech are the operational.
5 – If You do not speak in operational grammars then you do not speak truthfully, with warranty, particularly of warranty against externality.
6 – If you did not speak then we could merely avoid one another.
7 – And ergo, if you speak in critique (deceit, fraud, hazard) there is no reason to refrain from predation, since you have both voided boycott and cooperation.
