The strong nuclear force is actually the strongest of the four known forces and basically the glue that holds everything together. It is responsible for keeping protons and neutrons (which, along with electrons, form atoms) stable, and then allowing them to bind to atomic nuclei. The weak force, on the other hand, is responsible for radioactive decay, the opposite of the strong force, it controls how things collapse at the nuclear level. Oh and by the way, it is responsible for fusion and keeps our sun bright and warm. Goodman believed that the difference between natural laws and accidental truths was inextricably linked to the problem of induction. In his “The New Riddle of Induction” (1983, [f.p. 1954], page 73), Goodman says: These are the four forces without getting too caught up in the way these things work. But last year, a group of physicists from the Hungarian Academy of Sciences saw what the physics department at the University of California, Irvine (UCI) called “confusing anomalies in their experimental data.” The Hungarians were not sure what the anomalies were, but they pointed out the existence of a new type of light particle. That`s about all they did. They couldn`t figure out if this new particle had mass or if it was a new type of massless boson, like a photon.
The suggestion here is that there is the possibility of a universe without matter with the laws of general relativity and another with the laws of a contradictory theory of gravity. (For other examples, see Carroll 1994, 60-80). What Maudlin sees as a consequence of usual scientific reasoning, Humeans will see as an example that exposes the absurdity of non-supervenience. In this unit, we will explore the four forces of nature as they manifest themselves in gravity, electromagnetic radiation, and the structure of the atom. This brings us to a discussion about spectroscopy, the study of how to “decipher” the message of space light, the basic principles of optics, and how we build telescopes to collect and analyze light from space. Many features of the system approach are attractive. On the one hand, it is a challenge posed by empty laws. Some laws are empty: Newton`s first law of motion – that all inertial bodies have no acceleration – is a law, although there are no inertial bodies. But there are also many real empty non-laws: all plaid pandas weigh 5 pounds, not all unicorns are married, etc. With the systemic approach, there is no exclusion of empty generalizations from the domain of laws, and yet only empty generalizations that belong to the best systems are qualified (cf. Lewis 1986, 123). In addition, one of the goals of scientific theorization is the formulation of true theories that are balanced in their simplicity and strength.
The systems approach thus seems to underlie the truism that one of the goals of science is the discovery of laws (Earman 1978, 180; Loewer 1996, p. 112). A final aspect of the systems perspective that pleases many (but not all) is that it is consistent with the broadly humane limitations of reasonable metaphysics. There is no open appeal to closely related modal concepts (e.g., counterfactual conditions, causalities, dispositions) and no open appeal to entities providing modalities (e.g., universals or God; for the alleged need to appeal to God, see Foster, 2004). Indeed, the systemic approach is at the heart of Lewis`s defense of humaic supervenience, “the doctrine that all there is in the world is a vast mosaic of local affairs of certain facts, just a trifle and then another” (1986, ix). If one is a Humean, then the Humaean mosaic itself does not seem to allow any other explanation. Since this is the ontological foundation in which all other existing things must be explained, none of these other things can really explain the structure of the mosaic itself. This complaint has been expressed for a long time, usually as an objection to any humane presentation of laws. If laws are nothing more than generic features of the Humenic mosaic, then there is a sense in which these same laws cannot be invoked to explain the particular characteristics of the mosaic itself: laws are what they are by virtue of the mosaic and not the other way around (Maudlin 2007, 172).
In this regard, it is striking how little attention is paid to the possible effects of the context. Could it not be that if the economist utters a certain sentence of strict generalization in an “economic environment” (say, in an economics textbook or at an economic conference), contextual considerations that influence his conditions of truth will turn out to be true? This could be the case even if the same sentence is spoken in a different context (e.g. in a discussion between fundamental physicists or better still in a philosophical discussion of laws) would lead to a clearly false statement. These changing conditions of truth could be the result of something as obvious as a contextual shift in the field of quantification, or perhaps something less obvious. In any event, the important point is that this change could be based on nothing more than the linguistic meaning of the sentence and the familiar rules of interpretation (e.g., the accommodation rule). For example, van Fraassen, Giere and also Mumford believe that there are no laws. Van Fraassen finds support for his view in the problems faced by reports such as those of Lewis and Armstrong, and the perceived failure of Armstrong and others to describe an adequate epistemology that allows rational belief in laws (1989, 130, 180-181). Giere refers to the origins of the use of the concept of law in the history of science (1999 [f.p. 1995], 86-90) and argues that the generalizations often called laws are not in fact true (90-91). Mumford`s reasons are rather metaphysical; He argues that to govern, laws must be outside the qualities they govern, but to be external in this way, governed qualities do not need to have adequate identity conditions (2004, 144-145). Others adopt a subtly different type of anti-realism. Although they utter phrases such as “It is a law that no signal propagates faster than light”, they are anti-realist because they think that such sentences are not (purely) facts.
That this Einsteinian generalization is a law is not a fact about the universe; It`s not something waiting to be discovered. Reports of what laws are project only a certain attitude (in addition to belief) towards the generalizations they contain (Blackburn 1984, 1986, Ward 2002, 197). Ward adopts the attitude as such in terms of the relevance of generalization for prediction and explanation. In the late 1970s, a competitor for the systemic approach and all other humean attempts to say what it means to be a law emerged. Led by Armstrong (1978, 1983, 1991, 1993), Dretske (1977) and Tooley (1977, 1987), the rival approach uses universals (i.e., certain types of properties and relations) to distinguish laws from non-laws. Qn: The forces known to nature can be divided into four classes, namely gravity, electromagnetism, weak nuclear force and strong nuclear force. Which of the following statements is incorrect about them? For Roberts, a possible world in which there is only one particle moving at a constant speed throughout history and compared to a context where the salient theory is, for example, Newtonian mechanics, “It is a law that all particles have a constant velocity of one meter per second” is true. Just in case the reference to the “that” clause plays the role of the law in mainstream theory.
which is not the case here. It could play the role of law over another theory, but that would be a different context. A single generalization cannot play both the role of the law and the role of the law in relation to a single theory, and therefore another salient theory and therefore a different context is necessary for “It is a law that all bodies move at one meter per second” to be true (Roberts 2008, 357-61).
