68:6.4 When the [[land]] yield is reduced or the [[population]] is increased, the [[inevitable]] [[struggle]] is renewed; the very worst traits of [[human]] [[nature]] are brought to the [[surface]]. The improvement of the [[land]] yield, the extension of the [[mechanical]] arts, and the reduction of [[population]] all tend to foster the [[development]] of the better side of [[human]] [[nature]].

68:6.5 [http://en.wikipedia.org/wiki/Frontier Frontier] [[society]] [[develops]] the unskilled side of [[humanity]]; the [[fine art]]s and true [[scientific]] [[progress]], [[together]] with [[spiritual]] [[culture]], have all thrived best in the larger [[centers]] of life when [[supported]] by an [[agricultural]] and industrial [[population]] slightly under the land-man ratio. [[Cities]] always multiply the [[power]] of their [[inhabitants]] for either [[good]] or [[evil]].

68:6.6 The size of the [[family]] has always been [[influenced]] by the [[standards]] of living. The higher the standard the smaller the [[family]], up to the point of [[established]] [[status]] or [[gradual]] [[extinction]].

68:6.7 All down through the ages the standards of living have [[determined]] the [[quality]] of a [[surviving]] [[population]] in [[contrast]] with mere [[quantity]]. Local class standards of living give [[origin]] to new [[social]] [[castes]], new [[mores]]. When standards of living become too [[complicated]] or too highly [[luxurious]], they speedily become [[suicidal]]. [[Caste]] is the direct result of the high [[social]] [[pressure]] of keen [[competition]] produced by dense [[populations]].

68:6.8 The early races often resorted to [[practices]] designed to restrict [[population]]; all [[primitive]] [[tribes]] killed deformed and sickly [[children]]. Girl babies were frequently killed before the times of [[wife]] purchase. [[Children]] were sometimes strangled at [[birth]], but the favorite [[method]] was exposure. The [[father]] of twins usually insisted that one be killed since multiple [[births]] were believed to be caused either by [[magic]] or by infidelity. As a rule, however, twins of the same [[sex]] were spared. While these [[taboos]] on twins were once well-nigh [[universal]], they were never a part of the [http://en.wikipedia.org/wiki/ Andonite] [[mores]]; these peoples always regarded twins as omens of [[good]] [[luck]].

68:6.9 Many [[races]] learned the [[technique]] of [[abortion]], and this [[practice]] became very common after the [[establishment]] of the [[taboo]] on childbirth among the unmarried. It was long the [[custom]] for a maiden to kill her offspring, but among more civilized [[groups]] these illegitimate [[children]] became the wards of the girl's [[mother]]. Many [[primitive]] [[clans]] were [[virtually]] [[exterminated]] by the [[practice]] of both [[abortion]] and infanticide. But regardless of the dictates of the [[mores]], very few [[children]] were ever destroyed after having once been suckled—[[maternal]] [[affection]] is too strong.
