I think we are all a product of our own culture. We see everything through a veil of conditioning, this veil is worn by us from a very early age, and it is worn unwittingly by most of us. All of our learned ideas, consisting of everything we have absorbed from our surroundings, history, parents, taught religion (as we all tend to be more informed about a particular religion, than religion as a whole) media and peers, have been absorbed through this cultural veil, and these new absorbtions, over time, can add to the veil and define the way we see the world through its holes more.

It can often, and commonly is considered rude to leave a substantial amount of food on your plate. In Nepal, in the same scenario, to...

When you use the metaphor of a "veil" to descibe these presuppositions, it suggests that they are distorting, and that they hinder us from seeing things as they really are. That's certainly true for some of them: think of the history of sexist and racist ideas and how these were unquestioned for so long.

(Very early on, we all absorb some ethical views about how bad it is to needlessly hurt others, but I reckon these views are true, rather than distorting.) As a result of thinking...
