Do Physical Laws Make Things Happen?
Quote:The conviction that laws somehow give us a full accounting of events seems often to be based on the idea that they govern the world's substance or matter from outside, "making" things happen. If this is the case, however, then we must provide some way for matter to recognize and then obey these external laws. But, plainly, whatever supports this capacity for recognition and obedience cannot itself be the mere obedience. Anything capable of obeying wholly external laws is not only its obedience but also its capability, and this capability remains unexplained by the laws.
If, with so many scientists today, we construe laws as rules, we can put the matter this way: much more than rule-following is required of anything able to follow rules; conversely, no set of rules can by themselves explain the presence or functioning of that which is capable of following them.
It is, in other words, impossible to imagine matter that does not have some character of its own. To begin with, it must exist. But if it exists, it must do so in some particular manner, according to its own way of being. Even if we were to say, absurdly, that its only character is to obey external laws, this "law of obedience" itself could not be just another one of the external laws being obeyed. Something will be "going on" that could not be understood as obedience to law, and this something would be an essential expression of what matter was. To apprehend the world we would need to understand this expressive character in its own right, and we could never gain such an understanding solely through a consideration of external laws.
So we can hardly find coherence in the rather dualistic notion that physical laws reside, ghost-like, in some detached, abstract realm from which they impinge upon matter. But if, contrary to our initial assumption, we take laws to be in one way or another bound up with the world's substance — if we take them to be at least in part an expression of this substance — then the difficulty in the conventional view of law becomes even more intense. Surely it makes no sense to say that the world's material phenomena are the result — the wholly explained result — of matter obeying laws which it is itself busy expressing. In whatever manner we prefer to understand the material expression of the laws, this expression cannot be a matter of obedience to the laws being expressed! If whatever is there as the substance of the world at least in part determines the laws, then the laws cannot be said to determine what is there.
All this gives you some indication why so many scientists, when stepping back from the rather messy reality of their daily work and considering the character of their science, show such great reluctance to reckon with the substance of the observable world. They much prefer to conceive the explanatory value of science in terms of abstract laws — equations, rules, algorithms — which naturally remain gratifyingly lawful in an uncomplicated way. The world disappears into a vague notion of "whatever gives material reality to the laws".
But a willingness to consider this reality in its own terms immediately reveals the impossibility of the all-explaining laws with which science supposedly has to do. We come to realize that a physical phenomenon and its lawfulness must be considered as a unity — a syntactic-semantic unity of a sort that receives little recognition within science for the simple reason that physical phenomena (as opposed to their "governing" syntax) receive little recognition.
'Historically, we may regard materialism as a system of dogma set up to combat orthodox dogma...Accordingly we find that, as ancient orthodoxies disintegrate, materialism more and more gives way to scepticism.'
