Seeing this image gave me a moment of clarity about how evolution has probably worked
There must be a relation between capitalism and esotericism. The market is constituted by the pre-rational majority of society, which has been exploited for surplus capital, and what has that capital been used for? Separation from the animals that are exploited. Therefore there must be a history of secrecy in order for the exploiters of emotion and instinct to continue gathering surplus capital. Because as they continue to use their surplus capital to distance from the animals they develop a consciousness that the emotions of those same animals cannot understand and can only react to with anger, which means a loss of capital for the exploiters of these animals, hence esotericism follows.
