“When studies using mental ability test scores from children are considered, the heritability of mental ability is typically found to be about .40, and the effect of the common or shared environment is found to be almost as strong, about .35. In contrast, when studies using mental ability test scores from adults (or older adolescents) are considered, estimates of the heritability of mental ability are much higher, typically about .65, whereas estimates of common or shared environment effects are much lower, probably under .20 (see review by Haworth et al., 2010). These findings indicate that differences among children in their levels of mental ability are attributable almost as much to their common environment—that is, to features of their family or household circumstances—as to their genetic inheritances. However, the findings also suggest that as children grow up, the differences among them in mental ability become less strongly related to the features of their common environments, and more strongly related to their genetic inheritances. In other words, the effect on one's mental ability of the family or household in which one is reared tends to become less important as one grows up, so that by adulthood one's level of mental ability is heavily dependent on one's genetic characteristics. It is as if one's level of mental ability—relative to that of other persons of the same age—can be raised (or lowered) during childhood by a particularly good (or poor) home environment, but then gradually returns to the level that one's genes tend to produce.”

The aforementioned findings are based mainly on samples of participants who belong to the broad middle class of modern Western countries. There is some evidence, though, that the heritability of IQ tends to be somewhat lower (at least until young adulthood, and perhaps beyond) when studies are conducted using participants of less enriched environments, such as those in economically underdeveloped countries or in the lowest socioeconomic classes of some Western countries (see review by Nisbett et al., 2012). One recent study (Tucker-Drob & Bates, 2016) found that in the United States, additive genetic influences had a weaker influence on IQ among persons of low socioeconomic status than among persons of high socioeconomic status. (Interestingly, Tucker-Drob and Bates did not find this effect in western European countries or in Australia, where socioeconomic status differences tend to be smaller.) The above findings suggest that whenever the heritability of IQ is discussed, it is important to consider the ages of the persons being examined as well as their socioeconomic status and their country.”

“When suicide is out of fashion we conclude that none but madmen destroy themselves; and all the efforts of courage appear chimerical to dastardly minds ... Nevertheless, how many instances are there, well attested, of men, in every other respect perfectly discreet, who, without remorse, rage, or despair, have quitted life for no other reason than because it was a burden to them, and have died with more composure than they lived?”

“When superficially considered, the union of a creature with the creation would seem of great beauty. Such is the perception in what regards to a creature intimately united with its nature, covered by a veil perfectly adapted to such nature and that can be explained by this same nature. However, if we investigate this issue more carefully, we see that this beauty is only apparent and, in reality, such union reveals a prison. Because the spirit that gives life to this nature and with which is identified, the same that operates this field of reality and its creatures, represents a perfectly elaborated disunion in a carefully elaborated world of contradictions. In this universe, everything leads towards individualization. And the individual, to conquer his goals, has to adapt himself to the laws that govern his time and space; laws based on loneliness, suffering, and a struggle between life and death. These laws, expression of the vital spirit of this nature, lead to a great curse and an unexplainable suffering. And yet, these are laws to which the vast masses, with all their theories and behaviors towards self-preservation, accepts, while only a very small percentage of humanity desperately searches for an integration, unification with God, order, peace, balance, and harmony in this big house. The true integration consists in existentially vanishing from this field, through the union with another living spirit and the development of another existence that can adapt to this other living spirit. Therefore, we, that wish to travel along this path, must start by saying goodbye to this big house in this world, and move towards the paths of transformation and rebirth. Nonetheless, the natural state in which we are born, cannot allow a rebirth. In fact, it will oppose it and try to stop us, to preserve itself. That is why, when we wish to abandon this nature, this same nature will fight us, through its creatures and creations. This becomes more obvious when evident that we can’t be stopped through electromagnetic forces.”
