Toward the end of the sixteenth century, and in the very country which was to become the cradle of modern philosophy, there appeared, as a forerunner of the new thinking, a skepticism in which that was taken for complete and ultimate truth which with Descartes constitutes merely a moment or transition point in the inquiry. The earliest and the most ingenious among the representatives of this philosophy of doubt was Michel de Montaigne (1533-92), who in his Essays—which were the first of their kind and soon found an imitator in Bacon; they appeared in 1580 in two volumes, with an additional volume in 1588—combined delicate observation and keen thinking, boldness and prudence, elegance and solidity. The French honor him as one of their foremost writers. The most important among these treatises or essays is considered to be the "Apology for Raymond of Sabunde" (ii. 12) with valuable excursuses on faith and knowledge. Montaigne bases his doubt on the diversity of individual views, each man's opinion differing from his fellow's, while truth must be one. There exists no certain, no universally admitted knowledge. The human reason is feeble and blind in all things, knowledge is deceptive, especially the philosophy of the day, which clings to tradition, which fills the memory with learned note-stuff, but leaves the understanding void and, instead of things, interprets interpretations only. Both sensuous and rational knowledge are untrustworthy: the former, because it cannot be ascertained whether its deliverances conform to reality, and the latter, because its premises, in order to be valid, need others in turn for their own establishment, etc., ad infinitum. Every advance in inquiry makes our ignorance the more evident; the doubter alone is free. But though certainty is denied us in regard to truth, it is not withheld in regard to duty. In fact, a twofold rule of practical life is set up for us: nature, or life in accordance with nature and founded on self-knowledge, and supernatural revelation, the Gospel (to be understood only by the aid of divine grace). Submission to the divine ruler and benefactor is the first duty of the rational soul. From obedience proceeds every virtue, from over-subtlety and conceit, which is the product of fancied knowledge, comes every sin. Montaigne, like all who know men, has a sharp eye for human frailty. He depicts the universal weakness of human nature and the corruption of his time with great vivacity and not without a certain pleasure in the obscene; and besides folly and passion, complains above all of the fact that so few understand the art of enjoyment, of which he, a true man of the world, was master.
The skeptico-practical standpoint of Montaigne was developed into a system by the Paris preacher, Pierre Charron (1541-1603), in his three books On Wisdom (1601). Doubt has a double object: to keep alive the spirit of inquiry and to lead us on to faith. From the fact that reason and experience are liable to deception and that the mind has at its disposal no means of distinguishing truth from falsehood, it follows that we are born not to possess truth but to seek it. Truth dwells alone in the bosom of God; for us doubt and investigation are the only good amid all the error and tribulation which surround us. Life is all misery. Man is capable of mediocrity alone; he can neither be entirely good nor entirely evil; he is weak in virtue, weak in vice, and the best degenerates in his hands. Even religion suffers from the universal imperfection. It is dependent on nationality and country, and each religion is based on its predecessor; the supernatural origin of which all religions boast belongs in fact to Christianity alone, which is to be accepted with humility and with submission of the reason. Charron lays chief emphasis, however, on the practical side of Christianity, the fulfillment of duty; and the "wisdom" which forms the subject of his book is synonymous with uprightness (probité), the way to which is opened up by self-knowledge and whose reward is repose of spirit. And yet we are not to practice it for the sake of the reward, but because nature and reason, i.e., God, absolutely (entirely apart from the pleasurable results of virtue) require us to be good. True uprightness is more than mere legality, for even when outward action is blameless, the motives may be mixed. "I desire men to be upright without paradise and hell." Religion seeks to crown morality, not to generate it; virtue is earlier and more natural than piety. In his definition of the relation between religion and ethics, his delimitation of morality from legality, and his insistence on the purity of motives (do right, because the inner rational law commands it), an anticipation of Kantian principles may be recognized.
Under Francis Sanchez (died 1632; his chief work is entitled Quod Nihil Scitur), a Portuguese by birth, and professor of medicine in Montpellier and Toulouse, skepticism was transformed from melancholy contemplation into a fresh, vigorous search after new problems. In the place of book-learning, which disgusts him by its smell of the closet, its continued prating of Aristotle, and its self-exhaustion in useless verbalism, Sanchez desires to substitute a knowledge of things. Perfect knowledge, it is true, can be hoped for only when subject and object correspond to each other. But how is finite man to grasp the infinite universe? Experience, the basis of all knowledge, gropes about the outer surface of things and illumines particulars only, without the ability either to penetrate to their inner nature or to comprehend the whole. We know only what we produce. Thus God knows the world which he has made, but to us is vouchsafed merely an insight into mediate or second causes, causae secundae. Here, however, a rich field still lies open before philosophy—only let her attack her problem with observation and experiment rather than with words.
The French nation, predisposed to skepticism by its prevailing acuteness, has never lacked representatives of skeptical philosophy. The transition from the philosophers of doubt whom we have described to the great Bayle was formed by La Mothe le Vayer (died 1672; Five Dialogues, 1671), the tutor of Louis XIV., and P.D. Huet(ius), Bishop of Avranches (died 1721), who agreed in holding that a recognition of the weakness of the reason is the best preparation for faith.
6. %German Mysticism%.
In a period which has given birth to a skeptical philosophy, one never looks in vain for the complementary phenomenon of mysticism. The stone offered by doubt in place of bread is incapable of satisfying the impulse after knowledge, and when the intellect grows weary and despairing, the heart starts out in the quest after truth. Then its path leads inward, the mind turns in upon itself, seeks to learn the truth by inner experience and life, by inward feeling and possession, and waits in quietude for divine illumination. The German mysticism of Eckhart[1] (about 1300), which had been continued in Suso and Tauler and had received a practical direction in the Netherlands,—Ruysbroek (about 1350) to Thomas à Kempis (about 1450),—now puts forth new branches and blossoms at the turning point of the centuries.
[Footnote 1: Master Eckhart's Works have been edited by F. Pfeiffer, Leipsic, 1857. The following have written on him: Jos. Bach, Vienna, 1864; Ad. Lasson, Berlin, 1868; the same, in the second part of Ueberweg's Grundriss, last section; Denifle, in the Archiv für Litteratur und Kulturgeschichte des Mittelalters. ii. 417 seq.; H. Siebeck, Der Begriff des Gemuts in der deutschen Mystik (Beiträge zur Entstehungsgeschichte der neueren Psychologie, i), Giessen Programme, 1891.]
Luther himself was originally a mystic, with a high appreciation of Tauler and Thomas à Kempis, and published in 1518 that attractive little book by an anonymous Frankfort author, the German Theology. When, later, he fell into literalism, it was the mysticism of German Protestantism which, in opposition to the new orthodoxy, held fast to the original principle of the Reformation, i.e., to the principle that faith is not assent to historical facts, not the acceptance of dogmas, but an inner experience, a renewal of the whole man. Religion and theology must not be confounded. Religion is not doctrine, but a new birth. With Schwenckfeld, and also with Franck, mysticism is still essentially pietism; with Weigel, and by the addition of ideas from Paracelsus, it is transformed into theosophy, and as such reaches its culmination in Böhme.
Caspar Schwenckfeld sought to spiritualize the Lutheran movement and protested against its being made into a pastors' religion. Though he had been aroused by Luther's pioneer feat, he soon saw that the latter had not gone far enough; and in his Letter on the Eucharist, 1527, he defined the points of difference between Luther's view of the Sacrament and his own. Luther, he maintained, had fallen back to an historical view of faith, whereas the faith which saves can never consist in the outward acceptance of an historical fact. He who makes salvation dependent on preaching and the Sacrament, confuses the invisible and the visible Church, Ecclesia interna and externa. The layman is his own priest.
According to Sebastian Franck (1500-45), there are in man, as in everything else, two principles, one divine and one selfish, Christ and Adam, an inner and an outer man; if he submits himself to the former (by a timeless choice), he is spiritual, if to the latter, carnal. God is not the cause of sin, but man, who turns the divine power to good or evil. He who denies himself to live God is a Christian, whether he knows and confesses the Gospel or not. Faith does not consist in assent, but in inner transformation. The historical element in Christianity and its ceremonial observances are only the external form and garb (its "figure"), have merely a symbolic significance as media of communication, as forms of revelation for the eternal truth, proclaimed but not founded by Christ; the Bible is merely the shadow of the living Word of God.
