Seneca

“As the soil, however rich it may be, cannot be productive without cultivation, so the mind without culture can never produce good fruit.

Cultural norms are absorbed through the pores of our skin; they find there way into the cerebral regions and burn synaptic ruts that cause un-analyzed thoughts to form in our consciousness. These lazy thoughts are scattered throughout our minds in numerous heaps that may smell like dung (or is it the smell of decay), but one becomes accustomed to the odor or at least becomes distracted from it by the incessant necessity of consumption and amusement; a necessity that has been created from our cultural norms.

It is the rare individual that attempts to sort through the piles as it is difficult and unfamiliar work, and it may lead to rational and creative thought that may be viewed as insane. MR
