“In organisms of all kinds the young are launched upon their careers endowed with a certain amount of biological capital derived from their parents. This varies enormously in amount in different species, but, in all, there has been, before the offspring is able to lead an independent existence, a certain expenditure of nutriment in addition, almost universally, to some expenditure of time or activity, which the parents are induced by their instincts to make for the advantage of their young. Let us consider the reproductive value of these offspring at the moment when this parental expenditure on their behalf has just ceased. If we consider the aggregate of an entire generation of such offspring it is clear that the total reproductive value of the males in this group is exactly equal to the total value of all the females, because each sex must supply half the ancestry of all future generations of the species. From this it follows that the sex ratio will so adjust itself, under the influence of Natural Selection, that the total parental expenditure incurred in respect of children of each sex, shall be equal; for if this were not so and the total expenditure incurred in producing males, for instance, were less than the total expenditure incurred in producing females, then since the total reproductive value of the males is equal to that of the females, it would follow that those parents, the innate tendencies of which caused them to produce males in excess, would, for the same expenditure, produce a greater amount of reproductive value; and in consequence would be the progenitors of a larger fraction of future generations than would parents having a congenital bias towards the production of females. Selection would thus raise the sex-ratio until the expenditure upon males became equal to that upon females.”

Context: There is a certain amount of sham in. There is a certain amount of theatre. It’s as loosely knit as that. We’re sort of coming out of the closet a bit more over the next couple of years. We’re going to be bringing out – manifesto’s too pushy a word – if it’s a theatre of marvels, we’re bringing out a theatre programme in the next couple of years. We’re working on it at the moment – our unified field theory of spookiness where we try to explain everything from language, consciousness, grey aliens to Rosicrucianism or whatever. It is a grand, mad theory which I’m working my best on at the moment to make it rational. It is an anti-rationalistic theory but I’m trying to couch it in rational terms so that it is not as insular as a lot of magic stuff.

Context: Captain Hall expressed some doubts as to my views respecting the affection and love of pigeons, as if I made it human, and raised the possessors quite above the brutes. I presume the love of the mothers for their young is much the same as the love of woman for her offspring. There is but one kind of love; God is love, and all his creatures derive theirs from his; only it is modified by the different degrees of intelligence in different beings and creatures.

Context: There are men who live contented though they live without decorum. Others suffer as if in agony when they see around them people living without decorum. There must be a certain amount of decorum in the world, just as there must be a certain amount of light. When there are many men without decorum, there are always others who themselves possess the decorum of many men. These are the ones who rebel with terrible strength against those who rob nations of their liberty, which is to rob men of their decorum. Embodied in those men are thousands of men, a whole people, human dignity.
