Earwax in the canal. Jaw movement assists this process by dislodging debris attached to the walls of the ear canal, increasing the likelihood of its expulsion. The lubrication provided by cerumen prevents desiccation of the skin within the ear canal. The lubricative properties arise from the high lipid content of the sebum produced by the sebaceous glands. In wet-type cerumen, these lipids include cholesterol, squalene, and many long-chain fatty acids and alcohols. While studies conducted up until the 1960s found little evidence supporting antibacterial activity for cerumen, more recent studies have found that cerumen has a bactericidal effect on some strains
Theology of the Body In addition to the importance of power over nature, Descartes (like Bacon) insisted upon dismissing final cause, stating that “the entire class of causes which people customarily derive from a thing’s ‘end,’ I judge to be utterly useless”. Descartes’ practical philosophy also proposed a dualism between the mind and the physical body, based on the belief that they are two distinct substances. The body is matter that is spatially extended, whereas the mind is the substance that thinks and contains the rational soul.
