ONE:It is best, when an apprentice thinks of entering an engineering establishment, to inquire of its character from disinterested persons who are qualified to judge of the facilities it affords. As a rule, every machine-shop proprietor imagines his own establishment to combine all the elements of an engineering businessand the fewer the facilities for learners, usually the more extravagant this estimate; so that opinions in the matter, [24] to be relied upon, should come from disinterested sources.
TWO:A great reformer of the last generation, finding that the idea of Nature was constantly put forward to thwart his most cherished schemes, prepared a mine for its destruction which was only exploded after his death. Seldom has so powerful a charge of logical dynamite been collected within so small a space as in Mills famous Essay on Nature. But the immediate effect was less than might have been anticipated, because the attack was supposed to be directed against religion, whereas it was only aimed at an abstract metaphysical dogma, not necessarily connected with any theological beliefs, and held by many who have discarded all such beliefs. A stronger impression was, perhaps, produced by the nearly simultaneous declaration of Sir W. Gullin reference to the supposed vis medicatrix naturaethat, in cases of disease, what Nature wants is to put the man in his coffin. The new school of political economists have also done much to show that legislative interference with the natural laws of wealth need by no means be so generally mischievous as was once supposed. And the doctrine of Evolution, besides breaking down the old distinctions between Nature and Man, has represented the former as essentially variable, and therefore, to that extent, incapable of affording a fixed standard for moral action. It is, however, from this school that a new49 attempt to rehabilitate the old physical ethics has lately proceeded. The object of Mr. Herbert Spencers Data of Ethics is, among other points, to prove that a true morality represents the ultimate stage of evolution, and reproduces in social life that permanent equilibration towards which every form of evolution constantly tends. And Mr. Spencer also shows how evolution is bringing about a state of things in which the self-regarding shall be finally harmonised with the social impulses. Now, it will be readily admitted that morality is a product of evolution in this sense that it is a gradual formation, that it is the product of many converging conditions, and that it progresses according to a certain method. But that the same method is observed through all orders of evolution seems less evident. For instance, in the formation, first of the solar system, and then of the earths crust, there is a continual loss of force, while in the development of organic life there is as continual a gain; and on arriving at subjective phenomena, we are met by facts which, in the present state of our knowledge, cannot advantageously be expressed in terms of force and matter at all. Even if we do not agree with George Sand in thinking that self-sacrifice is the only virtue, we must admit that the possibility, at least, of its being sometimes demanded is inseparable from the idea of duty. But self-sacrifice cannot be conceived without consciousness; which is equivalent to saying that it involves other than mechanical notions. Thus we are confronted by the standing difficulty of all evolutionary theories, and on a point where that difficulty is peculiarly sensible. Nor is this an objection to be got rid of by the argument that it applies to all philosophical systems alike. To an idealist, the dependence of morality on consciousness is a practical confirmation of his professed principles. Holding that the universal forms of experience are the conditions under which an object is apprehended, rather than modifications imposed by an unknowable object on an unknowable subject, and that these50 forms are common to all intelligent beings, he holds also that the perception of duty is the widening of our individual selves into that universal self which is the subjective side of all experience.
THREE:It is not intended to recommend writing down rules or tables relating to shop manipulation so much as facts which require remark or comment to impress them on the memory; writing notes not only assists in committing the subjects to memory, but cultivates a power of composing technical descriptions, a very necessary part of an engineering education. Specifications for engineering work are a most difficult kind of composition and may be made long, tedious, and irrelevant, or concise and lucid.
