_Locke's Idea._--Mr. Locke strangely mistook the _evidence_ of personal identity for identity _itself_, and affirmed that our identity _consists_ in our consciousness. If this were so, then, whenever our consciousness were interrupted, as in sound sleep, or in fainting, or delirium, our identity would be gone. This error has been pointed out, and fully explained, by Dr. Reid, and Bishop Butler, the former of whom makes this supposition: that the same individual is, at different periods of life, a boy at school, a private in the army, and a military commander; while a boy, he is whipped for robbing an orchard; when a soldier, he takes a standard from the enemy, and at that time recollects, perfectly, the whipping when a boy; when commander, he remembers taking the standard but not the whipping. It follows, according to Mr. Locke, that the soldier is identical with the boy, and the general with the soldier, because conscious of the same things, but the general is not identical with the boy, because not conscious of the same things, that is, _a_ is _b_, and _b_ is _c_, yet _a_ is not _c_. The truth is, _identity_, and the _evidence_ of it, are two things. Were there no consciousness of any thing past, there would still be identity so long as unity and continuity of existence remained. _2. Identity as applied to the second Class._--As regards _organic material_ existence, whether animal or vegetable, the identity consists in that which constitutes the essence or being of the thing, which constitutes it an animal or vegetable existence. It is not mere body, not mere particles of matter, of such number and nature, or even of such arrangement and structure, but along with this, there is a higher principle involved--that of life. The continuity of this mysterious principle of life, under the same general structure and organization of material parts, making throughout one complex unity, one entity, one being, though with many changes, it may be, of separate parts and particles composing the organization; this constitutes the identity of the object.
