myself give a brief outline of European philosophy, for such comprehensive statements are not numerous. Moreover, for the benefit of competent students of philosophy, I desire to define my outlook. A preliminary survey of this character will prove helpful when we come to the description of individual Russian thinkers.
I shall confine myself to the later history of philosophy, beginning, like Radlov, with the eighteenth century.
First let us consider the problem of the philosophy of history.
The century of the enlightenment was characterised by the rise of the historic sense. Scientific historiography, the new method in history, begins with the latter half of the eighteenth century. Prior to this date the historic sense was lacking; there was no comprehension of the significance of comparing historical epochs, and there was no historical enlightenment. Chronology existed, but scientific history was unknown. This is not to say that there were no initial attempts at the new outlook, but the eighteenth century is the first we can speak of as thinking historically, the first century to secure a clear grasp of the concept of historical progress.
In the development and organisation of historical science, the profounder historic sense of the age was displayed in the scientific investigation of history, in the study of social life and its development. More especially was it manifest in the establishment of the new historical and sociological disciplines.
It was no chance matter that in every country numerous men of note became busied in this field. In his New Science, Vico produced the first philosophically planned treatise on sociology, a work in which the philosophy of history found a logical place as an integral constituent. French writers, in particular, devoted themselves to the philosophy of history. Voltaire was the first to use the term. Among other Frenchmen who were fruitful workers in this field may be mentioned Condorcet, Montesquieu, Target, and Rousseau. In Germany, we have Lessing, Herder, Schiller, and many other writers; and here, too, concrete historical investigation was methodically pursued (Schlözer, Schlosser, etc.). In England, Ferguson and other writers were at work, whilst Hume undertook historical research and wrote many sociological essays. The economic doctrines of Adam Smith have an important bearing upon sociology, and so have those of Malthus and the statisticians
