PREFACE TO THE FIRST EDITION, 1781\
|
|
\
|
|
Human reason, in one sphere of its cognition, is called upon to\
|
|
consider questions, which it cannot decline, as they are presented\
|
|
by its own nature, but which it cannot answer, as they transcend every\
|
|
faculty of the mind.\
|
|
\
|
|
It falls into this difficulty without any fault of its own. It\
|
|
begins with principles, which cannot be dispensed with in the field\
|
|
of experience, and the truth and sufficiency of which are, at the same\
|
|
time, insured by experience. With these principles it rises, in\
|
|
obedience to the laws of its own nature, to ever higher and more\
|
|
remote conditions. But it quickly discovers that, in this way, its\
|
|
labours must remain ever incomplete, because new questions never cease\
|
|
to present themselves; and thus it finds itself compelled to have\
|
|
recourse to principles which transcend the region of experience, while\
|
|
they are regarded by common sense without distrust. It thus falls into\
|
|
confusion and contradictions, from which it conjectures the presence\
|
|
of latent errors, which, however, it is unable to discover, because\
|
|
the principles it employs, transcending the limits of experience,\
|
|
cannot be tested by that criterion. The arena of these endless\
|
|
contests is called Metaphysic.\
|
|
\
|
|
Time was, when she was the queen of all the sciences; and, if we\
|
|
take the will for the deed, she certainly deserves, so far as\
|
|
regards the high importance of her object-matter, this title of\
|
|
honour. Now, it is the fashion of the time to heap contempt and\
|
|
scorn upon her; and the matron mourns, forlorn and forsaken, like\
|
|
Hecuba:\
|
|
\
|
|
Modo maxima rerum,\
|
|
Tot generis, natisque potens...\
|
|
Nunc trahor exul, inops.\
|
|
-- Ovid, Metamorphoses. xiii\
|
|
\
|
|
At first, her government, under the administration of the\
|
|
dogmatists, was an absolute despotism. But, as the legislative\
|
|
continued to show traces of the ancient barbaric rule, her empire\
|
|
gradually broke up, and intestine wars introduced the reign of\
|
|
anarchy; while the sceptics, like nomadic tribes, who hate a permanent\
|
|
habitation and settled mode of living, attacked from time to time\
|
|
those who had organized themselves into civil communities. But their\
|
|
number was, very happily, small; and thus they could not entirely\
|
|
put a stop to the exertions of those who persisted in raising new\
|
|
edifices, although on no settled or uniform plan. In recent times\
|
|
the hope dawned upon us of seeing those disputes settled, and the\
|
|
legitimacy of her claims established by a kind of physiology of the\
|
|
human understanding--that of the celebrated Locke. But it was found\
|
|
that--although it was affirmed that this so-called queen could not\
|
|
refer her descent to any higher source than that of common experience,\
|
|
a circumstance which necessarily brought suspicion on her claims--as\
|
|
this genealogy was incorrect, she persisted in the advancement of\
|
|
her claims to sovereignty. Thus metaphysics necessarily fell back into\
|
|
the antiquated and rotten constitution of dogmatism, and again\
|
|
became obnoxious to the contempt from which efforts had been made to\
|
|
save it. At present, as all methods, according to the general\
|
|
persuasion, have been tried in vain, there reigns nought but weariness\
|
|
and complete indifferentism--the mother of chaos and night in the\
|
|
scientific world, but at the same time the source of, or at least\
|
|
the prelude to, the re-creation and reinstallation of a science,\
|
|
when it has fallen into confusion, obscurity, and disuse from ill\
|
|
directed effort.\
|
|
\
|
|
For it is in reality vain to profess indifference in regard to\
|
|
such inquiries, the object of which cannot be indifferent to humanity.\
|
|
Besides, these pretended indifferentists, however much they may try\
|
|
to disguise themselves by the assumption of a popular style and by\
|
|
changes on the language of the schools, unavoidably fall into\
|
|
metaphysical declarations and propositions, which they profess to\
|
|
regard with so much contempt. At the same time, this indifference,\
|
|
which has arisen in the world of science, and which relates to that\
|
|
kind of knowledge which we should wish to see destroyed the last, is\
|
|
a phenomenon that well deserves our attention and reflection. It is\
|
|
plainly not the effect of the levity, but of the matured judgement*\
|
|
of the age, which refuses to be any longer entertained with illusory\
|
|
knowledge, It is, in fact, a call to reason, again to undertake the\
|
|
most laborious of all tasks--that of self-examination, and to\
|
|
establish a tribunal, which may secure it in its well-grounded claims,\
|
|
while it pronounces against all baseless assumptions and\
|
|
pretensions, not in an arbitrary manner, but according to its own\
|
|
eternal and unchangeable laws. This tribunal is nothing less than\
|
|
the critical investigation of pure reason.\
|
|
\
|
|
[*Footnote: We very often hear complaints of the shallowness of the\
|
|
present age, and of the decay of profound science. But I do not think\
|
|
that those which rest upon a secure foundation, such as mathematics,\
|
|
physical science, etc., in the least deserve this reproach, but that\
|
|
they rather maintain their ancient fame, and in the latter case,\
|
|
indeed, far surpass it. The same would be the case with the other\
|
|
kinds of cognition, if their principles were but firmly established.\
|
|
In the absence of this security, indifference, doubt, and finally,\
|
|
severe criticism are rather signs of a profound habit of thought.\
|
|
Our age is the age of criticism, to which everything must be\
|
|
subjected. The sacredness of religion, and the authority of\
|
|
legislation, are by many regarded as grounds of exemption from the\
|
|
examination of this tribunal. But, if they on they are exempted,\
|
|
they become the subjects of just suspicion, and cannot lay claim to\
|
|
sincere respect, which reason accords only to that which has stood\
|
|
the test of a free and public examination.]\
|
|
\
|
|
I do not mean by this a criticism of books and systems, but a\
|
|
critical inquiry into the faculty of reason, with reference to the\
|
|
cognitions to which it strives to attain without the aid of\
|
|
experience; in other words, the solution of the question regarding\
|
|
the possibility or impossibility of metaphysics, and the determination\
|
|
of the origin, as well as of the extent and limits of this science.\
|
|
All this must be done on the basis of principles.\
|
|
\
|
|
This path--the only one now remaining--has been entered upon by\
|
|
me; and I flatter myself that I have, in this way, discovered the\
|
|
cause of--and consequently the mode of removing--all the errors\
|
|
which have hitherto set reason at variance with itself, in the\
|
|
sphere of non-empirical thought. I have not returned an evasive answer\
|
|
to the questions of reason, by alleging the inability and limitation\
|
|
of the faculties of the mind; I have, on the contrary, examined them\
|
|
completely in the light of principles, and, after having discovered\
|
|
the cause of the doubts and contradictions into which reason fell,\
|
|
have solved them to its perfect satisfaction. It is true, these\
|
|
questions have not been solved as dogmatism, in its vain fancies and\
|
|
desires, had expected; for it can only be satisfied by the exercise\
|
|
of magical arts, and of these I have no knowledge. But neither do these\
|
|
come within the compass of our mental powers; and it was the duty of\
|
|
philosophy to destroy the illusions which had their origin in\
|
|
misconceptions, whatever darling hopes and valued expectations may\
|
|
be ruined by its explanations. My chief aim in this work has been\
|
|
thoroughness; and I make bold to say that there is not a single\
|
|
metaphysical problem that does not find its solution, or at least\
|
|
the key to its solution, here. Pure reason is a perfect unity; and\
|
|
therefore, if the principle presented by it prove to be insufficient\
|
|
for the solution of even a single one of those questions to which\
|
|
the very nature of reason gives birth, we must reject it, as we could\
|
|
not be perfectly certain of its sufficiency in the case of the others.\
|
|
\
|
|
While I say this, I think I see upon the countenance of the reader\
|
|
signs of dissatisfaction mingled with contempt, when he hears\
|
|
declarations which sound so boastful and extravagant; and yet they\
|
|
are beyond comparison more moderate than those advanced by the commonest\
|
|
author of the commonest philosophical programme, in which the\
|
|
dogmatist professes to demonstrate the simple nature of the soul, or\
|
|
the necessity of a primal being. Such a dogmatist promises to extend\
|
|
human knowledge beyond the limits of possible experience; while I\
|
|
humbly confess that this is completely beyond my power. Instead of\
|
|
any such attempt, I confine myself to the examination of reason alone\
|
|
and its pure thought; and I do not need to seek far for the\
|
|
sum-total of its cognition, because it has its seat in my own mind.\
|
|
Besides, common logic presents me with a complete and systematic\
|
|
catalogue of all the simple operations of reason; and it is my task\
|
|
to answer the question how far reason can go, without the material\
|
|
presented and the aid furnished by experience.\
|
|
\
|
|
So much for the completeness and thoroughness necessary in the\
|
|
execution of the present task. The aims set before us are not\
|
|
arbitrarily proposed, but are imposed upon us by the nature of\
|
|
cognition itself.\
|
|
\
|
|
The above remarks relate to the matter of our critical inquiry. As\
|
|
regards the form, there are two indispensable conditions, which any\
|
|
one who undertakes so difficult a task as that of a critique of pure\
|
|
reason, is bound to fulfil. These conditions are certitude and\
|
|
clearness.\
|
|
\
|
|
As regards certitude, I have fully convinced myself that, in this\
|
|
sphere of thought, opinion is perfectly inadmissible, and that\
|
|
everything which bears the least semblance of an hypothesis must be\
|
|
excluded, as of no value in such discussions. For it is a necessary\
|
|
condition of every cognition that is to be established upon a priori\
|
|
grounds that it shall be held to be absolutely necessary; much more\
|
|
is this the case with an attempt to determine all pure a priori\
|
|
cognition, and to furnish the standard--and consequently an example--\
|
|
of all apodeictic (philosophical) certitude. Whether I have\
|
|
succeeded in what I professed to do, it is for the reader to\
|
|
determine; it is the author's business merely to adduce grounds and\
|
|
reasons, without determining what influence these ought to have on\
|
|
the mind of his judges. But, lest anything he may have said may become\
|
|
the innocent cause of doubt in their minds, or tend to weaken the effect\
|
|
which his arguments might otherwise produce--he may be allowed to\
|
|
point out those passages which may occasion mistrust or difficulty,\
|
|
although these do not concern the main purpose of the present work.\
|
|
He does this solely with the view of removing from the mind of the\
|
|
reader any doubts which might affect his judgement of the work as a\
|
|
whole, and in regard to its ultimate aim.\
|
|
\
|
|
I know no investigations more necessary for a full insight into\
|
|
the nature of the faculty which we call understanding, and at the same\
|
|
time for the determination of the rules and limits of its use, than\
|
|
those undertaken in the second chapter of the "Transcendental\
|
|
Analytic," under the title of "Deduction of the Pure Conceptions of\
|
|
the Understanding"; and they have also cost me by far the greatest\
|
|
labour--labour which, I hope, will not remain uncompensated. The\
|
|
view there taken, which goes somewhat deeply into the subject, has\
|
|
two sides, The one relates to the objects of the pure understanding,\
|
|
and is intended to demonstrate and to render comprehensible the\
|
|
objective validity of its a priori conceptions; and it forms for\
|
|
this reason an essential part of the Critique. The other considers\
|
|
the pure understanding itself, its possibility and its powers of\
|
|
cognition--that is, from a subjective point of view; and, although\
|
|
this exposition is of great importance, it does not belong essentially\
|
|
to the main purpose of the work, because the grand question is what\
|
|
and how much can reason and understanding, apart from experience,\
|
|
cognize, and not, how is the faculty of thought itself possible? As\
|
|
the latter is an, inquiry into the cause of a given effect, and has\
|
|
thus in it some semblance of an hypothesis (although, as I shall\
|
|
show on another occasion, this is really not the fact), it would\
|
|
seem that, in the present instance, I had allowed myself to enounce\
|
|
a mere opinion, and that the reader must therefore be at liberty to\
|
|
hold a different opinion. But I beg to remind him that, if my\
|
|
subjective deduction does not produce in his mind the conviction of\
|
|
its certitude at which I aimed, the objective deduction, with which\
|
|
alone the present work is properly concerned, is in every respect\
|
|
satisfactory.\
