According to the process by which it is acquired, knowledge is intuitive and immediate or discursive and mediate. The former comes from the direct sense perception, or the direct mental intuition of the truth of a proposition, based as it were on its own merits. The latter consists in the recognition of the truth of a proposition by seeing its connection with another already known to be true. The self-evident proposition is of such a nature as to be immediately clear to the mind. No one who understands the terms can fail to know that two and two are four, or that the whole is greater than any one of its parts. But most human knowledge is acquired progressively. Inductive knowledge starts from self-evident facts, and rises to laws and causes. Deductive knowledge proceeds from general self-evident propositions in order to discover their particular application. In both cases the process may be long, difficult, and complex. One may have to be satisfied with negative conception and analogical evidence, and, as a result, knowledge will be less clear, less certain, and more liable to error.
