Duties are either positive or negative. If a duty is natural, then humans must be subject to that duty at birth. If one is subject to a duty, then she is capable of fulfilling it. Humans are not capable of fulfilling positive duties at birth and therefore are not subject to them. And so as humans are not subject to positive duties at birth, positive duties are not natural. Humans are capable, however, of fulfilling negative duties at birth (for to do so they need do nothing). In being capable of fulfilling these duties, it follows that humans are subject to them. So as it is the case that humans are subject to negative duties at birth, it follows that negative duties are natural. That which is natural is clearly prior to that which is artificial or conventional. Thereby anything artificial or conventional must come from something that is natural. However this is a self-contradiction. A pure duty is one that exists without a triggering action, and so there can be no pure positive duties
