2. Wherein that self-evidence consists.
Knowledge, as has been shown, consists in the perception of the agreement
or disagreement of ideas. Now, where that agreement or disagreement is perceived immediately by itself, without
the intervention or help of any other, there our knowledge is self-evident. This will appear to be so to any who
will but consider any of those propositions which, without any proof, he assents to at first sight: for in all of them
he will find that the reason of his assent is from that agreement or disagreement which the mind, by an immediate
comparing them, finds in those ideas answering the affirmation or negation in the proposition.
