Reason gives out as his own, and as a not insignificant product of his system, but which it is alleged had been given many years before by another writer, and almost in the same words.[1] I leave it to any one to judge whether the words: 'intellectualis quaedam constructio,' could have originated the thought of the presentation of a given conception in an intuitive perception a priori, by which Philosophy is at once entirely and definitely distinguished from Mathematics. I am certain that Hausen himself would have refused to recognise this as an explanation of his expression; for the possibility of an intuitive perception a priori, and the recognition of Space as such an intuition and not the mere outward coexistence of the manifold objects of empirical perception (as Wolf defines it), would have at once repelled him, on the ground that he would have felt himself thus entangled in wide philosophical investigations. The presentation, constructed, as it were, by the Understanding, referred to by the acute Mathematician, meant nothing more than the (empirical) representation of a Line corresponding to a conception, in making which representation attention is to be given merely to the Rule, and abstraction is to be made from the deviations from it that inevitably occur in actual execution, as may be easily perceived in the geometrical construction of Equalities.
And least of all is there any importance to be laid upon the objection made regarding the spirit of this Philosophy, on the ground of the improper use of some of its terms by those who merely ape the system in words. The technical expressions employed in the Critique of the Pure Reason cannot well be replaced by others in current use, but it is another thing to employ them outside of the sphere of Philosophy in the public interchange of ideas. Such a usage of them deserves to be well castigated, as Nicolai has shown; but he even shrinks from adopting the view that such technical terms are entirely dispensable in their own sphere, as if they were adopted merely to disguise a poverty of thought. However, the laugh may be much more easily turned upon the unpopular pedant than upon the uncritical ignoramus; for in truth the Metaphysician who sticks rigidly to his system without any concern about Criticism, may be reckoned as belonging to the latter class, although his ignorance is voluntary, because he will only not accept what does not belong to his own older school. But if, according to Shaftesbury's saying, it is no contemptible test of the truth of a predominantly practical doctrine, that it can endure Ridicule, then the Critical Philosophy must, in the course of time, also have its turn; and it may yet laugh best when it will be able to laugh last. This will be when the mere paper systems of those who for a long time have had the lead in words, crumble to pieces one after the other; and it sees all their adherents scattering away,—a fate which inevitably awaits them.
Towards the end of the work, I have treated several sections with less fulness of detail than might have been expected when they are compared with what precedes them. But this has been intentionally done, partly because it appears to me that the more general principles of the later subjects may be easily deduced from what has gone before; and, also, partly because the details of the Principles of Public Right are at present subjected to so much discussion, and are besides so important in themselves, that they may well justify delay, for a time, of a final and decisive judgment regarding them.

General Introduction to the Metaphysics of Morals
I.
The Relation of the Faculties of the Human Mind to the Moral Laws.
The Practical Faculty of Action.—The active Faculty of the Human Mind, as the Faculty of Desire in its widest sense, is the Power which man has, through his mental representations, of becoming the cause of objects corresponding to these representations. The capacity of a Being to act in conformity with his own representations, is what constitutes the Life of such a Being.
The Feeling of Pleasure or Pain.—It is to be observed, first, that with Desire or Aversion there is always connected Pleasure or Pain, the susceptibility for which is called Feeling. But the converse does not always hold. For there may be a Pleasure connected, not with the desire of an object, but with a mere mental representation, it being indifferent whether an object corresponding to the representation exist or not. And, second, the Pleasure or Pain connected with the object of desire does not always precede the activity of Desire; nor can it be regarded in every case as the cause, but it may as well be the Effect of that activity. The capacity of experiencing Pleasure or Pain on the occasion of a mental representation, is called 'Feeling,' because Pleasure and Pain contain only what is subjective in the relations of our mental activity. They do not involve any relation to an object that could possibly furnish a knowledge of it as such; they cannot even give us a knowledge of our own mental state. For even Sensations,[1] considered apart from the qualities which attach to them on account of the modifications of the Subject,—as, for instance, in reference to Red, Sweet, and such like,—are referred as constituent elements of knowledge to Objects, whereas Pleasure or Pain felt in connection with what is red or sweet, express absolutely nothing that is in the Object, but merely a relation to the Subject. And for the reason just stated, Pleasure and Pain considered in themselves cannot be more precisely defined. All that can be further done with regard to them is merely to point out what consequences they may have in certain relations, in order to make the knowledge of them available practically.
Practical Pleasure, Interest, Inclination.—The Pleasure, which is necessarily connected with the activity of Desire, when the representation of the object desired affects the capacity of Feeling, may be called Practical Pleasure. And this designation is applicable whether the Pleasure is the cause or the effect of the Desire. On the other hand, that Pleasure which is not necessarily connected with the Desire of an object, and which, therefore, is not a pleasure in the existence of the object, but is merely attached to a mental representation alone, may be called Inactive Complacency, or mere Contemplative Pleasure. The Feeling of this latter kind of Pleasure, is what is called Taste. Hence, in a System of Practical Philosophy, the Contemplative Pleasure of Taste will not be discussed as an essential constituent conception, but need only be referred to incidentally or episodically. But as regards Practical Pleasure, it is otherwise. For the determination of the activity of the Faculty of Desire or Appetency, which is necessarily preceded by this Pleasure as its cause, is what properly constitutes Desire in the strict sense of the term. Habitual Desire, again, constitutes Inclination; and the connection of Pleasure with the activity of Desire, in so far as this connection is judged by the Understanding to be valid according to a general Rule holding good at least for the individual, is what is called Interest. Hence, in such a case, the Practical Pleasure is an Interest of the Inclination of the individual. On the other hand, if the Pleasure can only follow a preceding determination of the Faculty of Desire, it is an Intellectual Pleasure, and the interest in the object must be called a rational Interest; for were the Interest sensuous, and not based only upon pure Principles of Reason, Sensation would necessarily be conjoined with the Pleasure, and would thus determine the activity of the Desire. Where an entirely pure Interest of Reason must be assumed, it is not legitimate to introduce into it an Interest of Inclination surreptitiously. However, in order to conform so far with the common phraseology, we may allow the application of the term 'Inclination' even to that which can only be the object of an 'Intellectual' Pleasure in the sense of a habitual Desire arising from a pure Interest of Reason. But such Inclination would have to be viewed, not as the Cause, but as the Effect of the rational Interest; and we might call it the non-sensuous or rational Inclination (propensio intellectualis).—Further, Concupiscence is to be distinguished from the activity of Desire itself, as a stimulus or incitement to its determination. It is always a sensuous state of the mind, which does not itself
