Exsiccata major
A schema is a configuration within the brain, either inborn or learned, against which the input of the nerve cells is compared. ...the conscious mind ...can fill in details that are missing from the actual sensory input and create a pattern in the mind which is not necessarily present in reality. In this way, the gestalt of objects—the impression...—is aided by the taxonomic powers of the schemata.
Primitive men are ecological analogs of lions, wolves, and hyenas... they have adopted pack hunting in the pursuit of big game. ...habitually slaughtering surplus prey, storing food, feeding solid food to their young, dividing labor, practicing cannibalism, and interacting aggressively with competing species. ...this way of life persisted for millions of years or longer and was abandoned in most societies only during the last few thousand years.
Pure knowledge is the ultimate emancipator. It equalizes people and sovereign states, erodes the archaic barriers of superstition and promises to lift the trajectory of cultural evolution. But I do not believe that it can change the ground rules of human behavior or alter the main course of history's predictable trajectory.
Animals use aggression as a technique for gaining control over necessities... that are scarce or are likely to become so... They intensify their threats and attack with increasing frequency as the population around them grow. As a result the behavior itself induces members of the population to spread out in space, raises the death rate, and lowers the birth rate. In such cases aggression is said to be a "density-dependent factor" in controlling population growth.
On Human Nature (1978)
If we were to vanish today, the land environment would return to the fertile balance that existed before the human population explosion. Only a dozen or so species, among which are the crab louse and a mite that lives in the oil glands of our foreheads, depend on us entirely. But if ants were to disappear, tens of thousands of other plant and animal species would perish also, simplifying and weakening land ecosystems almost everywhere.
