So far time has been wasted by many on discussing purity merely as a fact – that can either be true or false, objective or subjective, absolute or not absolute. We should move beyond the discussion of absolutes, because the Middle Way, reason itself, is being neglected: Purity is certainly a path. It is an ideal you pursue and a tradition you practise. Purity is a moral and social imperative. Discussing beauty as a fact, for example, will often lead to liberals answering that beauty is subjective – it is in the eye of the beholder. It does ultimately not matter whether beauty is subjective or objective or both.
What matters is that human beings naturally desire beauty. There is an evolutionary reason for this desire: It helps us survive. Desiring beauty improves our kind – being attracted to beauty is good for us. We can observe, i.e. detect, beauty for that reason. We have the natural ability to discriminate the beautiful – the ideal – from all others. Purity works like beauty – we desire it and we do not need purity to be an objective truth for we can desire it regardless.
