Crowley's theological beliefs were not clear. The historian Ronald Hutton noted that some of Crowley's writings could be used to argue that he was an atheist, [231] while some support the idea that he was a polytheist, [240] and others would bolster the idea that he was a mystical monotheist. [247]
The classical theories of evolution (mutation accumulation, antagonistic pleiotropy, and disposable soma) [1] [2] [3] suggest that environmental factors, such as predation, accidents, disease, and/or starvation, ensure that most organisms living in natural settings will not live until old age, and so there will be very little pressure to ...
The metabolic stability theory of aging suggests it is the cells ability to maintain stable concentration of ROS which is the primary determinant of lifespan. [37] This theory criticizes the free radical theory because it ignores that ROS are specific signalling molecules which are necessary for maintaining normal cell functions. [37]
Biogerontology should not be confused with geriatrics, which is a field of medicine that studies the treatment of existing disease in aging people, rather than the treatment of aging itself. There are numerous theories of aging, and no one theory has been entirely accepted. At their extremes, the wide spectrum of aging theories can be ...
Thelema (/ θ ə ˈ l iː m ə /) is a Western esoteric and occult social or spiritual philosophy [1] and a new religious movement founded in the early 1900s by Aleister Crowley (1875–1947), an English writer, mystic, occultist, and ceremonial magician. [2]
In biogerontology, the disposable soma theory of aging states that organisms age due to an evolutionary trade-off between growth, reproduction, and DNA repair maintenance. [1] Formulated by British biologist Thomas Kirkwood , the disposable soma theory explains that an organism only has a limited amount of resources that it can allocate to its ...
Strength of natural selection plot as a function of age. The antagonistic pleiotropy hypothesis (APT) is a theory in evolutionary biology that suggests certain genes may confer beneficial effects early in an organism's life, enhancing reproductive success, while also causing detrimental effects later in life, contributing to the aging process.
The theory considers the lifelong accumulation of developmental additions and subtractions, with the relative proportion of gains to losses diminishing over an individual's lifetime. [14] According to this theory, life span development has multiple trajectories (positive, negative, stable) and causes (biological, psychological, social, and ...
