Constructive dilemma [1] [2] [3] is a valid rule of inference of propositional logic. It is the inference that, if P implies Q and R implies S and either P or R is true, then either Q or S has to be true. In sum, if two conditionals are true and at least one of their antecedents is, then at least one of their consequents must be too.
The cut-elimination theorem for a calculus says that every proof involving Cut can be transformed (generally, by a constructive method) into a proof without Cut, and hence that Cut is admissible. The Curry–Howard correspondence between proofs and programs relates modus ponens to function application : if f is a function of type P → Q and x ...
Tinbergen's four questions, named after 20th century biologist Nikolaas Tinbergen, are complementary categories of explanations for animal behaviour. These are also commonly referred to as levels of analysis. [1] It suggests that an integrative understanding of behaviour must include ultimate (evolutionary) explanations, in particular:
The following is an example of a false dilemma with the simple constructive form: (1) "If you tell the truth, you force your friend into a social tragedy; and therefore, are an immoral person". (2) "If you lie, you are an immoral person (since it is immoral to lie)".
One example is the Defining Issues Test (DIT) created in 1979 by James Rest, [39] originally as a pencil-and-paper alternative to the Moral Judgement Interview. [40] Heavily influenced by the six-stage model, it made efforts to improve the validity criteria by using a quantitative test, the Likert scale, to rate moral dilemmas similar to ...
The word "cause" (or "causation") has multiple meanings in English.In philosophical terminology, "cause" can refer to necessary, sufficient, or contributing causes. In examining correlation, "cause" is most often used to mean "one contributing cause" (but not necessarily the only contributing cause).
A double bind is a dilemma in communication in which an individual (or group) receives two or more mutually conflicting messages. In some scenarios (e.g. within families or romantic relationships) this can be emotionally distressing, creating a situation in which a successful response to one message results in a failed response to the other (and vice versa), such that the person responding ...
In psychology, constructivism refers to many schools of thought that, though extraordinarily different in their techniques (applied in fields such as education and psychotherapy), are all connected by a common critique of previous standard approaches, and by shared assumptions about the active constructive nature of human knowledge. In ...
