The study of inbreeding depression seems to me especially important in the study of human abilities, because inbreeding depression indicates genetic dominance, and the presence and degree of dominance are related to natural selection for the trait in the course of its biological evolution. It was of great interest to me to discover, for example, that of the several ability factors that can be extracted from the various subtests of the Wechsler Intelligence Scale for Children, the one that shows the greatest susceptibility to inbreeding depression is the g factor (Jensen, 1983b). This finding indicates that one of our most widely used standard psychometric tests of intelligence yields scores that reflect some part of the variance in the biological intelligence that has developed in the course of human evolution.

What I mean by the "pursuit of learning" is not the ability to read classical texts and study ancient history, but to be fully acquainted with conditions all over the world and to have a keen awareness of what is going on abroad and around us. Now from what I can see world trends and conditions are still unsettled, and as long as they remain unsettled there is still a chance that something can be done. First, therefore, we must rectify conditions in our own domain, after which conditions in other domains can be rectified. This having been done, conditions at court can be rectified and finally conditions throughout the whole world can be rectified. First one must set an example oneself and then it can be extended progressively to others. This is what I mean by the "pursuit of learning."

General systems theory, in a sense, is no news at all, as Von Foerster found out when he attempted to organize a conference of general systems people and anthropologists. In a sense, the situation is comparable to that found by the Committee for the Study of Mankind, in which a committee that included Robert Redfidd tried to get each discipline to consider its relationship to the concept of Mankind. Anthropologists replied, "we are related already," and so they were. Something similar may be said of attempts to date in mathematical anthropology. The kind of information that a computer program can finally provide, on a level of a particular culture, is simply a reflection of how detailed field work has been done, and to the careful field worker, on kinship, for example, it provides no illumination.

The fundamental principle of the atheism of Spinoza is the doctrine of the simplicity of the universe, and the unity of that substance, in which he supposes both thought and matter to inhere. There is only one substance, says he, in the world; and that substance is perfectly simple and indivisible, and exists every where, without any local presence. Whatever we discover externally by sensation; whatever we feel internally by reflection; all these are nothing but modifications of that one, simple, and necessarily existent being, and are not possest of any separate or distinct existence. Every passion of the soul; every configuration of matter, however different and various, inhere in the same substance, and preserve in themselves their characters of distinction, without communicating them to that subject, in which they inhere.

It is great comedy to hear the secular, pro-gay left, so hostile to states' rights in virtually every instance, suddenly discover the tyranny of centralized government. The newly minted protectors of local rule find themselves demanding: "Why should Washington dictate marriage standards for Massachusetts and California? Let the people of those states decide for themselves.” This is precisely the argument conservatives and libertarians have been making for decades! Why should Washington dictate education, abortion, environment, and labor rules to the states? The American people hold widely diverse views on virtually all political matters, and the Founders wanted the various state governments to most accurately reflect those views. This is the significance of the 10th Amendment, which the left in particular has abused for decades.

Consider one of the standard "laments" or "stories of wonder" in conventional tales of natural history: the mayfly that lives but a single day (a sadness even recorded in the technical name for this biological group - Ephemoptera). Yes, the adult fly may enjoy only a moment in the sun, but we should honor the entire life cycle and recognize that the larvae, or juvenile stages, live and develop for months. Larvae are not mere preparations for a brief adulthood. We might better read the entire life cycle as a division of labor, with larvae as feeding and growing stages, and the adult as a short-lived reproductive machine. In this sense, we could well view the adult fly's day as the larva's clever and transient device for making a new generation of truly fundamental feeders.
