In the Ad Hominem section I made the claim that "physics is just ethicists trying to sound like something else", and Sam broke. Yet, in his crumbling state he did put forward two readings of what I could have meant, the second being more to the mark, that they are both normative systems. Now since Sam has claimed I lake all requisite wherewithal to argue such a case I won't try, but to fill out the picture a little more:
The laws of physics are produced (I make no claims about the laws themselves or those things which the laws describe, but about our awareness of what we refer to as the laws of physics) by observing how things work and then extrapolating. Ethics, similarly, is produced (in similar manner) by observing peoples actions and seeing which we react approbatively, and then extrapolating. Basically, they are both sets of 'laws' that only describe what we see, and do not in fact cause anything to act in certain manner as laws of society, from which the analogy is derived, are supposed to cause certain actions to be performed and cause certain actions not to be performed.
The laws of physics are taken to be different because we have never observed these laws being broken, while we have observed ethical systems being broken frequently. This may be purely because we have not yet formulated the ethical laws to the same degree as we have the physical, rather than because the systems are different. The physical laws certainly have gone through an amount of revision over time. Now I am not trying to suggest that the ethical laws could be brought to such precision as the physical, but that we understand the complexities of the ethical systems more than those of the physical: they are more personal. This of course is an argument that is produced purely through lack of knowledge, like so many other philosophical arguments at the moment, but the lack of knowledge is on both sides. Maybe the model of physical laws is only a model held up because we have limited knowledge of the system, which is upheld by theexistence of continuing work in the area of physics. So, 'physics is just ethics for matter'; what do you think?
