closure under known implication

Closure under known implication refers to the idea that if we know certain facts to be true, we can also recognize other truths that logically follow from them. In the context of general knowledge, it means that if we have a clear understanding of specific information, we can automatically accept additional information that is derived from what we already know. For instance, if you know it’s raining and understand that rain makes the ground wet, you can conclude that the ground is wet, even if you haven’t observed it directly.
