“The nature of this trade, certainly not the most honourable in the world, affords room for much investigation and remark in a moral or humane point of view: in a political or commercial light it is perhaps less conspicuously an object of attention. It consists chiefly of commodities that are considered as holding a first rate place in the animal and the mineral world, for which in return the Africans receive the most rascally articles that the ingenuity of Europeans has found means to produce. In return to our fellow creatures, for gold, and for ivory, we exchange the basest of those articles that are suited to the taste or the fancy of a despicable set of barbarians. Whether the spirituous liquirs or the fire-arms that are sent there are most calculated for the destruction of the purchasers, might become a question not very easy to determine. The noxious quality of the one is at least equalled by the danger of attending the use of the other. There does not seem to be that regard to honour in this trade, which ought to make part of the nice character of the English merchant, unimpeachable, unimpeached, upon the 'Change of London or of Amsterdam. It seems as if we kept our honour for ourselves, and that with those barbarians (who are more our inferiors in address and cunning, than perhaps in any thing else) no honour, humanity, or equity, were at all necessary.”

Context: Kekulé dreams the Great Serpent holding its own tail in its mouth, the dreaming Serpent which surrounds the World. But the meanness, the cynicism with which this dream is to be used. The Serpent that announces, "The World is a closed thing, cyclical, resonant, eternally-returning," is to be delivered into a system whose only aim is to violate the Cycle. Taking and not giving back, demanding that "productivity" and "earnings" keep on increasing with time, the System removing from the rest of the World these vast quantities of energy to keep its own tiny desperate fraction showing a profit: and not only most of humanity — most of the World, animal, vegetable, and mineral, is laid waste in the process. The System may or may not understand that it's only buying time. And that time is an artificial resource to being with, of no value to anyone or anything but the System, which must sooner or later crash to its death, when its addiction to energy has become more than the rest of the World can supply, dragging with it innocent souls all along the chain of life.

Context: The majority of parents are poor psychologists and give their children the most questionable moral trainings. It is perhaps in this domain that one realized most how keenly how immoral it can be to believe too much in morality, and how much more precious is a little humanity than all the rules in the world. Thus the adult leads the child to the notion of objective responsibility, and consolidates in consequence a tendency that is already natural to the spontaneous mentality of little children.
