From about the age of twelve, I entered into another and more advanced stage in my course of instruction; in which the main object was no longer the aids and appliances of thought, but the thoughts themselves. This commenced with Logic, in which I began at once with the Organon, and read it to the Analytics inclusive, but profited little by the Posterior Analytics, which belongs to a branch of speculation I was not yet ripe for. Contemporaneously with the Organon, my father made me read the whole or parts of several of the Latin treatises on the scholastic logic; giving each day to him, in our walks, a minute account of what I had read, and answering his numerous and searching questions. After this, I went in a similar manner, through the "Computatio sive Logica" of Hobbes, a work of a much higher order of thought than the books of the school logicians, and which he estimated very highly; in my own opinion beyond it merits, great as these are. It was his invariable practice, whatever studies he exacted from me, to make me as far as possible understand and feel the utility of them: and this he deemed peculiarly fitting in the case of the syllogistic logic, the usefulness of which had been impugned by so many writers of authority. I well remember how, and in what particular walk, in the neighbourhood of Bagshot Heath (where we were on a visit to his old friend Mr Wallace, then one of the Mathematical Professors at Sandhurst) he first attempted by questions to make me think on the subject, and frame some conception of what constituted the utility of the syllogistic logic, and when I had failed in this, to make me understand it by explanations. The explanations did not make the matter at all clear to me at the time; but they were not therefore useless; they remained as a nucleus for my observations and reflections to crystallize upon; the import of his general remarks being interpreted to me, by the particular instances which came under my notice afterwards. My own consciousness and experience ultimately led me to appreciate quite as highly as he did, the value of an early practical familiarity with the school logic. I know nothing, in my education, to which I think myself more indebted for whatever capacity of thinking I have attained. The first intellectual operation in which I arrived at any proficiency, was dissecting a bad argument, and finding in what part the fallacy lay: and though whatever capacity of this sort I attained was due to the fact that it was an intellectual exercise in which I was most perseveringly drilled by my father, yet it is also true that the school logic, and the mental habits acquired in studying it, were among the principal instruments of this drilling. I am persuaded that nothing, in modern education, tends so much, when properly used, to form exact thinkers, who attach a precise meaning to words and propositions, and are not imposed on by vague, loose, or ambiguous terms. The boasted influence of mathematical studies is nothing to it; for in mathematical processes, none of the real difficulties of correct ratiocination occur. It is also a study peculiarly adapted to an early stage in the education of philosophical students, since it does not presuppose the slow process of acquiring, by experience and reflection, valuable thoughts of their own. They may become capable of disentangling the intricacies of confused and self-contradictory thought, before their own thinking faculties are much advanced; a power which, for want of some such discipline, many otherwise able men altogether lack; and when they have to answer opponent, only endeavour, by such argument as they can command, to support the opposite conclusion, scarcely even attempting to confute the reasonings of their antagonists; and, therefore, at the utmost, leaving the question, as far as it depends on argument, a balanced one.
During this period also I commenced (and completed soon after I had left Parliament) the performance of a duty to philosophy and to the memory of my father, by preparing and publishing an edition of the "Analysis of the Phenomena of the Human Mind," with notes bringing up the doctrines of that admirable book to the latest improvements in science and in speculation. This was a joint undertaking: the psychological notes being furnished in about equal proportions by Mr Bain and myself, while Mr Grote supplied some valuable contributions on points in the history of philosophy incidentally raised, and Dr. Andrew Findlater supplied the deficiencies in the book which had been occasioned by the imperfect philological knowledge of the time when it was written. Having been originally published at a time when the current of metaphysical speculation ran in a quite opposite direction to the psychology of Experience and Association, the "Analysis" had not obtained the amount of immediate success which it deserved, though it had made a deep impression on many individual minds, and had largely contributed, through those minds, to create that more favourable atmosphere for the Association Psychology of which we now have the benefit. Admirably adapted for a class book of the Experience Metaphysics, it only required to be enriched, and in some cases corrected, by the results of more recent labours in the same school of thought, to stand, as it now does, in company with Mr Bain's treatises, at the head of the systematic works on Analytic psychology.
During the re-writing of the Logic, Dr. Whewell's Philosophy of the Inductive Sciences made its appearance; a circumstance fortunate for me, as it gave me what I greatly desired, a full treatment of the subject by an antagonist, and enabled me to present my ideas with greater clearness and emphasis as well as fuller and more varied development, in defending them against definite objections, or confronting them distinctly with an opposite theory. The controversies with Dr. Whewell, as well as much matter derived from Comte, were first introduced into the book in the course of the re-writing.
The same idea, that the use of my being in Parliament was to do work which others were not able or not willing to do, made me think it my duty to come to the front in defence of advanced Liberalism on occasions when the obloquy to be encountered was such as most of the advanced Liberals in the House, preferred not to incur. My first vote in the House was in support of an amendment in favour of Ireland, moved by an Irish member, and for which only five English and Scotch votes were given, including my own: the other four were Mr Bright, Mr McLaren, Mr T.B. Potter, and Mr Hadfield. And the second speech I delivered9 was on the bill to prolong the suspension of the Habeas Corpus in Ireland. In denouncing, on this occasion, the English mode of governing Ireland, I did no more than the general opinion of England now admits to have been just; but the anger against Fenianism was then in all its freshness; any attack on what Fenians attacked was looked upon as an apology for them; and I was so unfavourably received by the House, that more than one of my friends advised me (and my own judgment agreed with the advice) to wait, before speaking again, for the favourable opportunity that would be given by the first great debate on the Reform Bill. During this silence, many flattered themselves that I had turned out a failure, and that they should not be troubled with me any more. Perhaps their uncomplimentary comments may, by the force of reaction, have helped to make my speech on the Reform Bill the success it was. My position in the House was further improved by a speech in which I insisted on the duty of paying off the National Debt before our coal supplies are exhausted, and by an ironical reply to some of the Tory leaders who had quoted against me certain passages of my writings, and called me to account for others, especially for one in my "Considerations on Representative Government," which said that the Conservative party was, by the law of its composition, the stupidest party. They gained nothing by drawing attention to the passage, which up to that time had not excited any notice, but the sobriquet of "the stupid party" stuck to them for a considerable time afterwards. Having now no longer any apprehension of not being listened to, I confined myself, as I have since thought too much, to occasions on which my services seemed specially needed, and abstained more than enough from speaking on the great party questions. With the exception of Irish questions, and those which concerned the working classes, a single speech on Mr Disraeli's Reform Bill was nearly all that I contributed to the great decisive debates of the last two of my three sessions.
