Power over nature was not to be individual but collective; the Empire, as he says, of Man over Nature, substituted for the Empire of Man over Man. Let us employ Bacon's own words with their variety of picturesque metaphor: "Men have entered into the desire of learning and knowledge,... seldom sincerely to give a true account of their gift of reason, to the benefit and use of men, but as if they sought in knowledge a couch whereon to rest a searching and wandering spirit; or a terrace for a wandering and variable mind to walk up and down with a fair prospect; or a tower for a proud mind to raise itself upon; or a fort or commanding ground for strife and contention; or a shop for profit and sale; and not a rich storehouse for the glory of the creator and the relief of man's estate." When William James called Pragmatism a New Name for an Old Way of Thinking, I do not know that he was thinking expressly of Francis Bacon, but so far as concerns the spirit and atmosphere of the pursuit of knowledge, Bacon may be taken as the prophet of a pragmatic conception of knowledge. Many misconceptions of its spirit would be avoided if his emphasis upon the social factor in both the pursuit and the end of knowledge were carefully observed.

This somewhat over-long résumé of Bacon's ideas has not been gone into as a matter of historic retrospect. The summary is rather meant to put before our minds an authentic document of the new philosophy which may bring into relief the social causes of intellectual revolution. Only a sketchy account can be here attempted, but it may be of some assistance even barely to remind you of the direction of that industrial, political and religious change upon which Europe was entering.

Upon the industrial side, it is impossible, I think, to exaggerate the influence of travel, exploration and new commerce which fostered a romantic sense of adventure into novelty; loosened the hold of traditional beliefs; created a lively sense of new worlds to be investigated and subdued; produced new methods of manufacture, commerce, banking and finance; and then reacted everywhere to stimulate invention, and to introduce positive observation and active experimentation into science. The Crusades, the revival of the profane learning of antiquity and even more perhaps, the contact with the advanced learning of the Mohammedans, the increase of commerce with Asia and Africa, the introduction of the lens, compass and gunpowder, the finding and opening up of North and South America—most significantly called The New World—these are some of the obvious external facts. Contrast between peoples and races previously isolated is always, I think, most fruitful and influential for change when psychological and industrial changes coincide with and reinforce each other. Sometimes people undergo emotional change, what might almost be called a metaphysical change, through intercourse. The inner set of the mind, especially in religious matters, is altered. At other times, there is a lively exchange of goods, an adoption of foreign tools and devices, an imitation of alien habits of clothing, habitation and production of commodities. One of these changes is, so to speak, too internal and the other too external to bring about a profound intellectual development. But when the creation of a new mental attitude falls together with extensive material and economic changes, something significant happens.

This coincidence of two kinds of change was, I take it, characteristic of the new contacts of the sixteenth and seventeenth centuries. Clash of customs and traditional beliefs dispelled mental inertia and sluggishness; it aroused a lively curiosity as to different and new ideas. The actual adventure of travel and exploration purged the mind of fear of the strange and unknown: as new territories geographically and commercially speaking were opened up, the mind was opened up. New contacts promoted the desire for still more contacts; the appetite for novelty and discovery grew by what it fed upon. Conservative adherence to old beliefs and methods underwent a steady attrition with every new voyage into new parts and every new report of foreign ways. The mind became used to exploration and discovery. It found a delight and interest in the revelations of the novel and the unusual which it no longer took in what was old and customary. Moreover, the very act of exploration, of expedition, the process of enterprising adventure into the remote, yielded a peculiar joy and thrill.

This psychological change was essential to the birth of the new point of view in science and philosophy. Yet alone it could hardly have produced the new method of knowing. But positive changes in the habits and purposes of life gave objective conformation and support to the mental change. They also determined the channels in which the new spirit found exercise. Newfound wealth, the gold from the Americas and new articles of consumption and enjoyment, tended to wean men from preoccupation with the metaphysical and theological, and to turn their minds with newly awakened interest to the joys of nature and this life. New material resources and new markets in America and India undermined the old dependence upon household and manual production for a local and limited market, and generated quantitative, large scale production by means of steam for foreign and expanding markets. Capitalism, rapid transit, and production for exchange against money and for profit, instead of against goods and for consumption, followed.

This cursory and superficial reminder of vast and complicated events may suggest the mutual interdependence of the scientific revolution and the industrial revolution. Upon the one hand, modern industry is so much applied science. No amount of desire to make money, or to enjoy new commodities, no amount of mere practical energy and enterprise, would have effected the economic transformation of the last few centuries and generations. Improvements in mathematical, physical, chemical and biological science were prerequisites. Business men through engineers of different sorts, have laid hold of the new insights gained by scientific men into the hidden energies of nature, and have turned them to account. The modern mine, factory, railway, steamship, telegraph, all of the appliances and equipment of production, and transportation, express scientific knowledge. They would continue unimpaired even if the ordinary pecuniary accompaniments of economic activity were radically altered. In short, through the intermediary of invention, Bacon's watchword that knowledge is power and his dream of continuous empire over natural forces by means of natural science have been actualized. The industrial revolution by steam and electricity is the reply to Bacon's prophecy.

On the other hand, it is equally true that the needs of modern industry have been tremendous stimuli to scientific investigation. The demands of progressive production and transportation have set new problems to inquiry; the processes used in industry have suggested new experimental appliances and operations in science; the wealth rolled up in business has to some extent been diverted to endowment of research. The uninterrupted and pervasive interaction of scientific discovery and industrial application has fructified both science and industry, and has brought home to the contemporary mind the fact that the gist of scientific knowledge is control of natural energies. These four facts, natural science, experimentation, control and progress have been inextricably bound up together. That up to the present the application of the newer methods and results has influenced the means of life rather than its ends; or, better put, that human aims have so far been affected in an accidental rather than in an intelligently directed way, signifies that so far the change has been technical rather than human and moral, that it has been economic rather than adequately social. Put in the language of Bacon, this means that while we have been reasonably successful in obtaining command of nature by means of science, our science is not yet such that this command is systematically and pre-eminently applied to the relief of human estate. Such applications occur and in great numbers, but they are incidental, sporadic and external. And this limitation defines the specific problem of philosophical reconstruction at the present time. For it emphasizes the larger social deficiencies that require intelligent diagnosis, and projection of aims and methods.

It is hardly necessary to remind you however that marked political changes have already followed upon the new science and its industrial applications, and that in so far some directions of social development have at least been marked out. The growth of the new technique of industry has everywhere been followed by the fall of feudal institutions, in which the social pattern was formed in agricultural occupations and military pursuits. Wherever business in the modern sense has gone, the tendency has been to transfer power from land to financial capital, from the country to the city, from the farm to factory, from social titles based on personal allegiance, service and protection, to those based on control of labor and exchange of goods. The change in the political centre of gravity has resulted in emancipating the individual from bonds of class and custom and in producing a political organization which depends less upon superior authority and more upon voluntary choice. Modern states, in other words, are regarded less as divine, and more as human works than they used to be; less as necessary manifestations of some supreme and over-ruling principles, and more as contrivances of men and women to realize their own desires.

The contract theory of the origin of the state is a theory whose falsity may easily be demonstrated both philosophically and historically. Nevertheless this theory has had great currency and influence. In form, it stated that some time in the past men voluntarily got together and made a compact with one another to observe certain laws and to submit to certain authority and in that way brought the state and the relation of ruler and subject into existence. Like many things in philosophy, the theory, though worthless as a record of fact, is of great worth as a symptom of the direction of human desire. It testified to a growing belief that the state existed to satisfy human needs and could be shaped by human intention and volition. Aristotle's theory that the state exists by nature failed to satisfy the thought of the seventeenth century because it seemed by making the state a product of nature to remove its constitution beyond human choice. Equally significant was the assumption of the contract theory that individuals by their personal decisions expressing their personal wishes bring the state into existence. The rapidity with which the theory gained a hold all over western Europe showed the extent to which the bonds of customary institutions had relaxed their grip. It proved that men had been so liberated from absorption in larger groups that they were conscious of themselves as individuals having rights and claims on their own account, not simply as members of a class, guild or social grade.

Side by side with this political individualism went a religious and moral individualism. The metaphysical doctrine of the superiority of the species to the individual, of the permanent universal to the changing particular, was the philosophic support of political and ecclesiastical institutionalism. The universal church was the ground, end and limit of the individual's beliefs and acts in spiritual matters, just as the feudal hierarchical organization was the basis, law and fixed limit of his behavior in secular affairs. The northern barbarians had never completely come under the sway of classic ideas and customs. That which was indigenous where life was primarily derived from Latin sources was borrowed and more or less externally imposed in Germanic Europe. Protestantism marked the formal breaking away from the domination of Roman ideas. It effected liberation of individual conscience and worship from control by an organized institution claiming to be permanent and universal. It cannot truly be said that at the outset the new religious movement went far in promoting freedom of thought and criticism, or in denying the notion of some supreme authority to which individual intelligence was absolutely in bonds. Nor at first did it go far in furthering tolerance or respect for divergency of moral and religious convictions. But practically it did tend to disintegration of established institutions. By multiplying sects and churches it encouraged at least a negative toleration of the right of individuals to judge ultimate matters for themselves. In time, there developed a formulated belief in the sacredness of individual conscience and in the right to freedom of opinion, belief and worship.
