Ebook Elements of Logic

Logic ought to exhibit this other way likewise: it ought to inform us how the most original premises arise, and upon what basis they rest. Other methods, indeed, have been abroad in the world, but without being systematically propounded as parts of Logic.

And the Novum Organum of Bacon contains a logical exposition of the method of establishing first principles through the observa tion of phenomena.
