Term: 
Possibility
Quote: 

We certainly have the notion of objective possibility, whether there be such a thing or not. It may be defined as that mode of being which is not subject to the principle of contradiction since if it be merely possible that A is B, it is possible that A is not B. [—] How can the principle of contradiction fail to apply to anything? By something being held in reserve and not expressed.
