The drought is a fine instance of the argument that just because you can buy something – in this case, as much water as you like, even with penalty pricing – doesn't mean you should.
This may suggest that some skeptical proponents of the sources project aim to motivate an instance of the Argument from Unreliability (§3.3).
In particular, they seem easily able to handle any instance of that argument that builds upon a case of manipulation in which an agent is massively altered at a moment in time, say by being given a Frankfurtian desire structure that she previously lacked, or by having numerous reasons-responsive mechanisms installed in an instant.
Our coding of the arguments presented in both committee hearings and floor debates allowed us to match the types of arguments made (where each mention of a particular issue counts as an instance of that argument) with the states and the strength of legislation.
A famous instance of this type of argument is the Cartesian argument for global skepticism, according to which the hypothesis that reality is more or less the way we customarily deem it to be is empirically equivalent to a variety of so-called skeptical hypotheses (such as that we are beguiled by an evil demon, or that we are brains in a vat, connected to a supercomputer).
Understanding it in this way — as an instance of visual argument — allows us to analyze and evaluate it with the tools of analysis and assessment that informal logic has developed (whether additional tools are needed to assess such arguments remains an open question).
In this respect, the argument appears to be an instance of a "local" argument for occasionalism in that the scope of the argument is limited to a particular type of substance.
Once we recognize the argumentative structure of the advertisement, we can go further, and consider whether it should be understood as an instance of an argument scheme (a standard pattern of argument).
For instance, this argument indicates that the SOPs of the two beams cannot relax towards, e.g., a linear state, because such a relaxation would violate the symmetry properties of the fiber.
Indeed, by repetition of this argument all instances of a0 must have the same colour.
