leaf and delicate fiber! In the same way will the ever-growing tree of human consciousness and life appear in philosophy, whenever it is not torn from its roots and stripped of its leaves by a pretended wisdom, but is vividly apprehended by a true science, and exhibited and presented to the mind in its life and its growth. Not only, however, the arrangement of the whole, but also the connection of the several parts of a philosophical treatise or development, is of a higher kind than any mere mechanical joining, such, for instance, as that by which two pieces of wood are nailed or glued together. If I must illustrate this connection by a simile from animated nature, the facts of magnetism will best serve my purpose. Once magnetically excited, the iron needle comes into invisible contact and connection with the whole globe and its opposite poles; and this magnetic clew has guided the bold circumnavigator into new and unknown regions of the world. Now, the intrinsic vital coherence of the several thoughts of philosophy resembles this magnetic attraction; and no such rude, mechanical, and, in fact, mere external conjunction of thought, like that lately alluded to, can satisfy the requirements of philosophical connection. But the supreme intrinsic unity of philosophical thought, or of a philosophical series of ideas, is quite different from every thing hitherto mentioned. It belongs not to nature, but to life; it is not derived from the latter by way of figure or illustration, but is a part and constituent of it, and goes to the very root and soil of the moral life. What I mean is, the unity of sentiment--the fixed character, remaining ever the same and true to itself--the inner necessary sequence of the thoughts--which, in life no less than in the system and philosophical theory, invariably makes a great and profound impression on our minds, and commands our respect, even when it does not carry along with it our convictions. This, however, is dependent on no form, and no mere method can attain to it. How often, for instance, in some famous political harangue, which perhaps the speaker, like the rhapsodist of old, poured forth on the spur of the moment, do we at once recognize and admire this character in the thoughts, this consistency of sentiment? How often, on the contrary, in another composed with the most exquisite research and strict method, and apparently a far more elaborate and finished creation of the intellect, we have only to pierce through the systematic exterior to find that it is nothing but an ill-connected and chance-medley of conflicting assumptions and opinions taken from all quarters, and the crude views of the author himself, devoid of all solidity, and resting on no firm basis, without character, and wholly destitute of true intrinsic unity?
