The dangers to faith in the present day are sometimes exaggerated; but there cannot be a doubt that we live in a time when old creeds are in peril; when the doubt is the result not of ignorance, but of knowledge, and acts in the minds that are pre-eminent for intellectual influence, and advances with a firmness that is not to be repelled by force but by argument. It is not the duty of Christians to shut their eyes to the danger, like the ostrich, which supposes by burying her eyes in the sand to avoid the huntsman's arrow. There seems accordingly special reason why in such an age an acquaintance with the forms of doubt is requisite on the part of those who have to minister the religion which is the subject of attack.
If accordingly a clergy is to be trained up likely to supply the intellectual cravings of the present day, they must be placed on a level with its ripest knowledge, and be acquainted with the nature and origin of the forms of doubt which they will encounter. The church has indeed a large field, where work and not thought is to be the engine which the clergy must use in their labours; truly a home mission, where men and women for whom Christ died, require to be lifted out of their mere animalism, and taught the simplest truths [pg 344] of Christ, and prayer, and immortality: and noble are the efforts that Christians have made, and are making, for an object so religious and philanthropic; but there is a danger lest this very energy of work, which accords so naturally with the utilitarianism of the English character, should lead us to forget that there is an opposite stratum of society, to which also Christianity has its message, which is only to be reached by the delicate gifts of intellect and by the ripest learning.
If Christianity is to be presented to this class, adapted to the demands of the age so far as they are reasonable, but unmutilated and unaltered in its body of revealed doctrine, preserving in its integrity the faith delivered to the saints; so that apostles might recognize it as being that which they themselves taught, and for which they laid down their lives; it is necessary that Christian students should be trained specially for the work, by a learned and intelligent appreciation of truth, such as will create orthodoxy without bigotry, and charity without latitude. If we have to dread their going forth with hesitating opinions, teaching, through their very silence concerning the mysterious realities which constitute the very essence of Christianity, another gospel than that which was once for all miraculously revealed; there is almost equal ground for alarm if they go forth, able only to repeat the shibboleths of a professional creed, and unable to give a reason of the glorious hope that is in them. In the former case they will fail to teach historic and dogmatic Christianity, because they do not believe it; in the latter because they do not understand its meaning and evidence. If they need piety as the first requisite, they need knowledge as the second. In certain conditions of the church, study is second only to prayer itself as an instrument for the Christian evangelist.
It is hoped, therefore, that a sketch of a department not previously treated as a whole, may indirectly be an aid to the Christian faith, if it shall perform the humble office of supplying some elements of instruction to the Christian student.
Such a purpose however would hardly have justified the introduction of the subject here. The motive which dictated its consideration was much more practical. It was hoped that the answer to many species of doubt would be found by referring them to the forms of thought or of philosophy from which they had sprung; that it would be possible to perceive how they might be refuted, by understanding why and how men have come to believe them.[1010] This is a study of mental pathology seldom undertaken. The practical aim of Christian writers has generally suggested to them a readier mode of treating the history of unbelief, by referring its origin to intellectual pride; and, if any margin remained unaccounted for by this explanation, to refer it to an invisible agent, the direct operation of Satan.[1011] Such a method, however true, commits the error, against which Bacon utters a warning, of ascending at once to the most general causes without interpolating the intermediate. It ignores the intellectual class of causes, and omits to trace the subtlety of their mode of manifestation;—a problem equally interesting, whether they be regarded as original causes of doubt, or only as secondary instruments obeying the impulse of the emotional causes. It would have been possible to investigate the subject, by selecting a few leading instances to illustrate the natural history of doubt; but the most likely mode for exhausting the subject, as well as for presenting it in a manner which would fall in with the historic tastes of the age, seemed to be, to treat it by means of a critical history, presenting the antidote by a running criticism; and to ask, frankly and fully, what have been the grounds on which Christianity has been doubted; and what have been those on which the faith of Christians in their hour of peril has reposed; and then finally to gather up the lessons which the history itself teaches.
The inquiry has been analogous to the study of the history of a disease; and scientific rigour required that it should be conducted with a similar spirit of fairness towards those that manifest its symptoms. As the physiologist, who wishes to learn the laws of a disease, watches patiently the symptoms in the subject of it, not reproaching the sufferer, even if the malady be self-caused; so in moral diagnosis, the student of mental and religious error must carry out his inquiries in the spirit of cold analysis, if he would arrive at the real character of the intricate facts which he studies. The candour of our examination has not been prompted by any spirit of indifference to truth, nor by sympathy with error; but partly by the demands of historical accuracy, partly by deep pity for those who are the subject of spiritual doubts, even when the doubts are of their own fault.
This view of the inquiry, as an analysis of the intellectual causes of doubt, will also explain one or two peculiarities in it, which, if left unnoticed, might leave an impression of its inutility.
It will be seen, for example, that in the investigation of the natural history of doubt, and in the explanation of the antecedent metaphysical or critical questions which have produced it, we have indicated the schools of thought which have created it, but have abstained from insisting on the inherent necessity of the relation which subsists between the metaphysical tests of truth and the religious conclusions discussed. The reason is, that it seemed unfit to assume a side eagerly in the metaphysical controversy; and therefore, while showing that the use of certain grounds of belief and methods of inquiry has produced, both as a matter of history and logic, certain species of doubt or disbelief; we have not attempted to condemn the particular metaphysical theories on the ground of the logical consequences which are supposed to flow from them, nor to deny that they could be so amended, as either to avoid the sceptical conclusions to which our objections are taken, or be rendered innocuous by the co-existence [pg 347] of other causes. Science only shows the general tendency or law of logical connection between intellectual causes and effects. The production of the results in particular cases is subject to exception from the introduction of interfering causes.[1012]
Another peculiarity which appertains to the analysis of the intellectual sources of doubt, besides the seeming absence of invariable necessity in their operation, might be thought to destroy the practical value of the inquiry; viz. the feeling of disappointment excited when it is perceived that they do not wholly explain the phenomenon, and are merely antecedents or elements, not causes. This arises from the very nature of mental analysis. Being in nature like chemical, it aims only at the detection of the elements that make up the compound, and furnishes the material or formal causes, not the efficient. This longing of the mind to find causes, and to discover the original motive power, is however a witness to the ineffaceable connection of the idea of power with that of will. And while it does not destroy the completeness of the analysis, as the solution of the intellectual problem proposed, it nevertheless points to the instinctive wish of the heart to resolve the causes of doubt into some ultimate source in the will; and is thus a witness to the truth of the position which we have always asserted,[1013] that the intellectual causes selected for our special study are only one branch, and must be united to the emotional in order to attain a full explanation of the phenomenon of doubt.
Thus the analysis offered will have, it is hoped, a utility in the limited sphere which was claimed for it, in supplying the account of the tangled and subtle processes through which doubt has insinuated itself.
