Disjunctive Conditional Quote by John Stuart Mill
““An example of this is, when the simple propositions are connected by the particle or; as, either A is B or C is D; or by the particle if; as, A is B if C is D. In the former case, the proposition is called disjunctive, in the latter, conditional: the name hypothetical was originally common to both.””

![“[For people] to refuse a hearing to an opinion, because they are sure that it is false, is to assume that their certainty is the same thing as absolute certainty. All silencing of discussion is an assumption of infallibility.” quote by John Stuart Mill](https://sms4smile.com/quotes/img-quotes/c53/john-stuart-mill-477_doubt_for-people-to-refuse-a-hearing-to-an-opi_63929.jpg)
