While there is no one conditional premise of the conditional form which is false, it is nonetheless true according to supervaluation theory that some conditional is.
Accepting the standard (three-valued) truth-conditions for the universal quantifier, Soames (1999) takes the conditional sorites to have some non-true conditional premise.
The conclusion of the conditional form is resisted by noticing that some conditional premise fails to be true; though, admittedly, none is false.
He did not make a conditional promise.
Pointers was not the only important Avicennan text in later Arabic logic: post-Avicennan logicians mined the Cure's volume on the Prior Analytics for the syllogistic with conditional premises, a syllogistic which they modified perhaps even more than they modified Avicenna's modal syllogistic (see Khûnajî 2010: section 10; see also El-Rouayheb's Introduction, xlv xlviii).
Moreover, if the acceptability of a statement is defined as having a value greater than j for 0 < j < 1 and all the conditional premises of the Sorites Paradox do not fall below the value j, then modus ponens does not preserve acceptability, because the conclusion of the Sorites Argument, being evaluated as 0, is unacceptable.
The premise is that the engagement ring is a conditional gift — the condition being that a marriage take place.
Although the courts there generally accept the premise that an engagement ring is a conditional gift, he said that in a 2003 decision: "the court decided that if the donor was the one who broke the promise, then the recipient could keep it.
What is the difference between the roles of a premise, and of the antecedent of a conditional in the conclusion?
In fact, one can also evaluate the truth conditions of conditionals under this point of view by saying that a conditional is true if an argument from the antecedent and suitable co-tenable premises to the conditional's conclusion exists.
Moreover, as the concept of a conditional was also meant to provide for logical consequence between premises and conclusion, this leads to the problematic result that arguments can in principle change from being valid to being invalid and vice versa.
