Purity, some say it can only be achieved with one of clear and mind and soul. Others believe children, are born pure. All of these are man's assumption on what is considered flawless and pristine.However, nobody is flawless. So how can anybody be "Pure"? Perhaps it can only be achived by non-organic means. A robot can surely imbune this quality since it is what one molds into what they think is pure; to each his own.
