Another valid form of argument is known as constructive dilemma or sometimes just 'dilemma'. It does not leave the user with one statement alone at the end of the argument, instead, it gives an option of two different statements. The first premise gives an option of two different statements.
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 ...
A dilemma that Kohlberg used in his original research was the druggist's dilemma: Heinz Steals the Drug In Europe. Other stories on moral dilemma that Kohlberg used in his research were about two young men trying to skip town, both steal money to leave town but the question then becomes whose crime was worse out of the two.
In logic, the law of excluded middle or the principle of excluded middle states that for every proposition, either this proposition or its negation is true. [1] [2] It is one of the three laws of thought, along with the law of noncontradiction, and the law of identity; however, no system of logic is built on just these laws, and none of these laws provides inference rules, such as modus ponens ...
The concept of construal is not a new one, and the components of construal can be seen in the works of many past psychologists including Kurt Lewin's recognition of the importance of a subjective reality and its effect on one's personal significance; Kurt Koffka's theories of gestalt psychology; Brunswik's emphasis on subjective distinction ...
A dilemma (from Ancient Greek δίλημμα (dílēmma) 'double proposition') is a problem offering two possibilities, neither of which is unambiguously acceptable or preferable. The possibilities are termed the horns of the dilemma, a clichéd usage, but distinguishing the dilemma from other kinds of predicament as a matter of usage. [1]
Moral disengagement is a meaning from developmental psychology, educational psychology and social psychology for the process of convincing the self that ethical standards do not apply to oneself in a particular context. [1] [2] This is done by separating moral reactions from inhumane conduct and disabling the mechanism of self-condemnation. [3]
