The judgment formed on this epoch of free thought, when we have separated from it the Protestantism which craves other satisfaction for the human mind than that which is implied in submission to human authority, and the scepticism which was merely transitional doubt, must be condemnatory. The unbelief was indeed a phase of the general improvement; but one which is instructive as a warning rather than as an example, illustrating the abuse not the use of free thought. The evil nevertheless was temporary, and belongs to the past; the good was eternal: and the elements of real intellectual improvement contained in the struggle have been taken up into the constitution of modern thought and society.
We have now considered three great epochs in the history of free thought, and watched Christianity in contact or conflict with the old heathen philosophy, with the thought Scholastic or Mahometan of the middle ages, and with the revival of classical learning. It remains to enter upon the consideration of the fourth, and to observe it in relation to modern science.
The seventeenth century introduced as striking a revolution in philosophy as the corresponding ones which the two preceding ages had produced in literature and religion.
Two distinct thinkers, Bacon and Descartes, from different points of view, perceived the necessity for constructing a new method of inquiry. Their position was similar to that of Socrates of old. They saw that if knowledge was to be rendered sound, it must be based on a new method.[331] They both alike sought it in experience; Bacon in sensational, Descartes in intellectual, [pg 106] the instinctive utterance of consciousness.[332] The indirect effects on religion produced by their teaching will be seen more fully hereafter. Our present object is to sketch the influence exercised by Descartes on the theological speculations of Spinoza, before passing in succeeding lectures to the detailed study of those peculiarities which free thought has presented in the different countries in which it has been manifested.[333]
Spinoza's memory has been branded with the stigma which attached to his character during life.[334] Born in Holland, of Jewish origin, his early repudiation of the legends of the Talmud in which he was educated, caused his excommunication by his own people. Finding himself an outcast, he sought society among a few sceptical friends, one of whom was a physician named Van den Ende, whom a sense of injustice united to him by the [pg 107] bond of common sympathy. His life was passed in retirement, in hard, griping poverty. Possessing a mind of great originality, and a fondness for demonstrative reasoning never surpassed, he lived a model of chaste submissive virtue, searching for speculative truth; branded as an atheist in philosophy while living, and regarded since his death as the parent of many of the worst forms of rationalism in religion. Yet his character is one that cannot fail to excite a certain kind of pity. Unlike the frivolous selfish atheism, the immoral Epicureanism, of the French unbelief of the following century, his investigations were grave, his tone dignified, his temper gentle, his spirit serious. It is to be feared that he did not worship God; but he at least worshipped, at the cost of social martyrdom, what he thought to be truth. If he did not believe in revealed religion, he at least tried to embody what he believed to be its moral precepts. Though we may shrink with horror from his teaching, we cannot, when we compare him with other unbelievers, withhold our pity from the teacher.
His works are short, but weighty. Of his important treatises, the one, the Tractatus Theologico-Politicus, shows him as the Biblical critic; the other, the Ethica, exhibits his philosophy. In the former, written in early life, he derives his materials and mode of handling from the Jewish mediæval theologian Maimonides; in the latter, the product of his riper years, from Descartes.[335] But he had undoubtedly come under the influence of Descartes before writing the former work, and it is certain that the effects of it on his own philosophical [pg 108] scheme are already discernible in it. We shall therefore commence with the latter, and attempt to understand his philosophy, and its application to religion, before studying his special criticism of Revelation.
Descartes had aimed, like the great thinkers of earlier times, to gain a general view of the universe of being; but had sought it by a different mode. Caring rather for certitude of method, reality in the highest principles, than for results attained, he had seen that a knowledge of being must rest on a knowledge of the consciousness which tells us of being. His principle, “Cogito, ergo sum,” is the expression of this conviction. Therefore, carrying analysis into the human mind, he had grasped those ideas which appeal to us with irresistible clearness, and commend themselves as axioms requiring no proof; and from these ideas, or rather from the idea of cause, the primitive of them, regarded by him as innate, he had demonstrated à priori the being and attributes of God, and the principles which dominate in the great fields of knowledge.[336]
Spinoza's object was similar; but he sought to attain it in a different manner: rejecting, on the one hand, the dualism by which Descartes had opposed mind and matter, he regarded each as a different mode of the same primitive substance, and, on the other, the limited idea of the divine Being, he conceived that the mind of man realizes the notion of Him as unlimited. There are three different opinions in reference to our capacity of knowing the infinity of God. Either our knowledge of Him is only negative and relative; we know only what He is not, and our positive notions of His nature are drawn from the analogy of human personality; or, secondly, we have an intuition of His infinity, but so bare of attributes, that while it guarantees the reality of our apprehensions of Him, we are dependent on experience for its development into a conception; or, thirdly, the human mind can apprehend His infinity positively, antecedent to the application of limitations [pg 109] to it.[337] The last of these three views belonged to Spinoza, along with the ancient Eleatics, the Neo-Platonists of the early ages, and the principal schools of modern German philosophy. Accordingly he tried to work out with mathematical rigour in geometrical form a philosophy of existence, conceiving that the mind grasps the idea of God as infinite substance, and understands its development under two modes; viz. extension and thought: the former the objective act of Deity, the latter the subjective.[338] The universe therefore is nothing but the manifestation of God: God is the sum total of it; the unity in its variety; the infinite comprehending its finity. Cause and effect are identical; the natura naturans, and natura naturata. Causation is change; but it is nothing but substance assuming attributes, and attributes assuming modes. Phenomena are only the bubbles which arise on the bosom of the ocean and disappear, absorbed in its vastness. The universe is bound in one vast chain of fatalism, one grand and perfect whole. Man's perfection is to know by contemplation the universe in which he has his being.
Such a system has been called atheistic, because it is silent about the presence of a personal first Cause. It might be more truly denominated Pantheistic, not in the vague sense in which that term is applied to denote the belief in a Deity as an anima mundi, like that explained in reference to the Averroists,[339] but to imply that the sum total of all things, the universe, is Deity. Its influence on the question of revealed religion will be obvious. It admits that the phenomena which we attribute to miracle in the process of revelation are facts, but it denies their miraculous character.[340] They are the mere manifestation of some previously unknown law, turning up accidentally at the particular moment, some previously unknown mode in which the all-embracing substance manifests itself. In [pg 110] this view all religions become various expressions of the great moral and spiritual truths which they embody, and true piety consists in rising beyond them to the vision of the higher truths which they typify, and the practice of the principles which they enjoin as rules. “Dico,” wrote Spinoza, “ad salutem non esse omnino necesse, Christum secundum carnem noscere; sed de æterno illo filio Dei, hoc est, Dei æternâ sapientiâ quæ sese in omnibus rebus, et maxime in mente humana et omnium maxime in Christo Jesu manifestavit, longe aliter sentiendum.”[341]
