a man's own mind.’ Brown (Philosophy of the Mind, pp. 67, 68) denies that consciousness is a faculty: and Sir W. Hamilton complains of ‘Reid's degradation of consciousness into a special faculty.’ Notes to Reid's Works, pp. 223, 297, 373. M. Cousin (Hist. de la Philosophie, II. Série, vol. i. p. 131) pronounces consciousness to be ‘phénomène complexe;’ and at p. 94, ‘la condition nécessaire de l'intelligence c'est la conscience:’ while a still later writer (Jobert's New System of Philosophy, vol. i. p. 25) declares that ‘we have the consciousness of our consciousness – this is certain.’ The statement in Alciphron, Dialogue vii. (Berkeley's Works, vol. i. pp. 505, 506) is equally unsatisfactory: and what still further perplexes the question is the existence of what is now recognised as ‘double consciousness.’ See on this extraordinary phenomenon Elliotson's Physiology, pp. 367–369, 1165; Mayo's Physiology, pp. 195, 196; Prichard's Treatise on Insanity, pp. 450, 451; Carpenter's Human Physiology, p. 379.

This requires explanation. Consciousness is infallible as to the fact of its testimony; but fallible as to the truth. That we are conscious of certain phenomena, is a proof that those phenomena exist in the mind, or are presented to it; but to say that this demonstrates the truth of the phenomena is to go a step further, and not only offer a testimony, but also pass a judgment. The moment we do this, we introduce the element of fallibility; because consciousness and judgment put together cannot be always right, inasmuch as judgment is often wrong.

The late Blanco White, a thinker of considerable subtlety, says: ‘The important distinction between libertas a necessitate and libertas a coactione, is seldom attended to. Nothing whatever can force my will: every man is more or less conscious of that fact: but at the same time we are, or may be, equally conscious that we are never decided without a motive.’ Life of B. White, by Himself, 1845, vol. iii. p. 90. But how can a man be conscious ‘that nothing whatever can force his will’? This is not consciousness, but judgment: it is a judgment of what may be, not a consciousness of what is. If there is any meaning in the word ‘consciousness,’ it must refer solely to the present, and can never include future contingencies as to what may be or can be.

As Herder says, ‘Was diese Nation ihrem Gedankenkreise unentbehrlich hält, daran hat jene nie gedacht oder hält es gar für schädlich.’ Ideen zur Gesch. der Menschheit, vol. ii. p. 130.

Plato was struck by the extreme difficulty of finding a standard in the human mind whereby we may test the truth or falsehood of spectral phenomena and dreams. And the only conclusion to which this consummate thinker could arrive, was that whatever appears true to the individual mind is true for him: which, however, is an evasion of the problem, not a solution of it. See the Theætetus, where Plato, as usual, puts his own speculations into the mouth of Socrates. He opens the question at the beginning of sec. 39 (Platonis Opera, vol. iii. p. 426, edit. Bekker, Lond. 1826), Μὴ τοίνυν ἀπολίπωμεν ὃσον ἐλλεῖπον αὐτοῦ. λείπεται δὲ ἐνυπνίων τε πέρι καὶ νόσων, τῶν τε ἄλλων καὶ μανίας, &c. These are the supposed sources of error; but Socrates, after discussing them, and entangling Theætetus in a maze, sums up at the end of sec. 45, p. 434, ἁληθὴς ᾰρα ἐμοὶ ἡ ἐμὴ αῐσθησις. See further, p. 515, on the formation of erroneous judgments; and respecting the assertions made by many of the Greeks that πᾶσα φαντασία ἀληθὴς and πᾶσα δύξα ἀληθὴς, compare Cudworth, vol. iii. p. 379, vol. iv. p. 118. For physiological considerations concerning the preservation of consciousness in dreams and in insanity, see Broussais, Examen des Doctrines Médicales, vol. i. p. 406; his Cours de Phrénologie, p. 49; Esquirol, Maladies Mentales, vol. i. p. 97, vol. ii. p. 790; Simon's Pathology, p. 204; Holland's Medical Notes, p. 434; Henle, Anatomie Générale, vol. ii. p. 287; Burdach, Traité de Physiologie, vol. v. p. 223. See, too, the passages in Tennemann which connect this difficulty with the theory of representation (Geschichte der Philosophie, vol. i. p. 357, vol. ii. pp. 119, 159, vol. iii. p. 406, vol. iv. p. 418); and the attempt of Berkeley (Works, vol. i. pp. 93, 101, 176) to turn it into a defence of his own system, on the ground that our belief respecting the external world may be as false when we are awake as when we dream. The solution offered by the Stoics is merely a verbal and unproved distinction: διαφέρει δὲ φαντασία καὶ φάντασμα. φάντασμα μὲν γάρ ἐστι δόκησις διανοίας οἴα γίνται κατὰ τοὺς ὔπνους⋅ φαντασία δέ ἐστι τύπωσις ἐν ψυχῇ τουτέστιν ἀλλοίωσις, ὡς ὁ Χρύσιππος ἐν τῇ δνωδεκάτη περὶ ψυῆς ὐφίσταται Diog. Laert. de Vitis Philos. lib. vii. segm. 50, vol. i. p. 395.

Meaning by free will, a cause of action residing in the mind, and exerting itself independently of motives. If any one says that we have this power of acting without motives, but that in the practical exercise of the power we are always guided by motives either conscious or unconscious – if any one says this, he asserts a barren proposition, which does not interfere with my views, and which may or may not be true, but which most assuredly no one has ever yet succeeded in proving.

That is, according to the phenomenal evidence presented to the understanding, and estimated by the ordinary logic with which the understanding is conversant. But Kant has made a most remarkable attempt to avoid the practical consequences of this, by asserting that freedom, being an idea produced by the reason, must be referred to transcendental laws of the reason; that is, to laws which are removed from the domain of experience, and cannot be verified by observation. In regard, however, to the scientific conceptions of the understanding (as distinguished from the Reason) he fully admits the existence of a Necessity destructive of Liberty. In Note A, at the end of this chapter, I shall put together the most important passages in which Kant unfolds this view.

This is, of course, an hypothetical case, merely given as an illustration. We never can know the whole of any man's antecedents, or even the whole of our own; but it is certain that the nearer we approach to a complete knowledge of the antecedent, the more likely we shall be to predict the consequent.

The doctrine of providential interference is bound up with that of predestination, because the Deity, foreseeing all things, must have foreseen His own intention to interfere. To deny this foresight, is to limit the omniscience of God. Those, therefore, who hold that, in particular cases, a special providence interrupts the ordinary course of events, must also hold that in each case the interruption had been predestined; otherwise they impeach one of the Divine attributes. For, as Thomas Aquinas puts it (Neander's History of the Church, vol. viii. p. 176), ‘knowledge, as knowledge, does not imply, indeed, causality; but in so far as it is a knowledge belonging to the artist who forms, it stands in the relation of causality to that which is produced by his art.’

The same argument is stated by Alciphron, though not quite so conclusively; Dialogue vii. sec. 20 in Berkeley's Works, vol. i. p. 515: and as to the impossibility of Omniscience having new knowledge or an afterthought, see Hitchcock's Religion of Geology, 1851, pp. 267, 328; an ingenious work, but one which leaves all the real difficulties untouched. Compare Ritter's Hist. of Ancient Philos. vol. iv. pp. 326, 327, with Tennemann, Gesch. der Philos. vol. vi. pp. 151, 342–345, vol. ix. pp. 81–94, vol. xi. p. 178; and in particular, the question raised (vol. viii.
