In “The Layout of Arguments,” Stephen Toulmin’s thesis is that a new framework is needed for argumentation, as an alternative to the syllogism. The framework (or layout) he proposes involves a claim made due to some data, a warrant (often implicit) given to support the inference of the claim from the data, possibly a qualification added to the claim along with conditions of exception, and backing supplied to provide sufficient grounds for a warrant. Toulmin claims that the syllogism is too ambiguous because, for instance, universal premises (such as “All men are mortal”) do not properly distinguish between warrant and backing. Additionally, with a syllogism one cannot always tell whether a universal premise is true only in theory or in existential, empirical fact. Toulmin explains that logicians have too long relied on the syllogism and that in doing so they have forced arguments into a mold that doesn’t take into account subtle distinctions.
Notable Quotes
- "It is at this physiological level that the idea of logical form has been introduced, and here that the validity of our arguments has ultimately to be established or refuted" (105).
- "The existence of considerations such as would establish the acceptability of the most reliable warrants is something we are entitled to take for granted" (115).
- "No entirely general answer can be given to the question, for what determines whether there are or are not existential implications in any particular case is not the form of statement itself, but rather the practical use to which this form is put on that occasion" (123).
- "If we are to set our arguments out with complete logical candor, and understand properly the nature of the 'the logical process,' surely we shall need to emply a pattern of argument no less sophisticated than is required by law" (107).
- "Even the most general warrants in ethical arguments are yet liable in unusual situations to suffer exceptions, and so at strongest can authorize only presumptive conclusions" (125).
