The history of philosophy (the same writer observes) contains instances of systems, which for successive generations have remained enigmatic. Such he deems the system of Leibnitz, whom another writer (rashly I think, and invidiously) extols as the only philosopher, who was himself deeply convinced of his own doctrines. As hitherto interpreted, however, they have not produced the effect, which Leibnitz himself, in a most instructive passage, describes as the criterion of a true philosophy; namely, that it would at once explain and collect the fragments of truth scattered through systems apparently the most incongruous. The truth, says he, is diffused more widely than is commonly believed; but it is often painted, yet oftener masked, and is sometimes mutilated and sometimes, alas! in close alliance with mischievous errors. The deeper, however, we penetrate into the ground of things, the more truth we discover in the doctrines of the greater number of the philosophical sects. The want of substantial reality in the objects of the senses, according to the sceptics; the harmonies or numbers, the prototypes and ideas, to which the Pythagoreans and Platonists reduced all things: the ONE and ALL of Parmenides and Plotinus, without [49] Spinozism; the necessary connection of things according to the Stoics, reconcilable with the spontaneity of the other schools; the vital-philosophy of the Cabalists and Hermetists, who assumed the universality of sensation; the substantial forms and entelechies of Aristotle and the schoolmen, together with the mechanical solution of all particular phaenomena according to Democritus and the recent philosophers--all these we shall find united in one perspective central point, which shows regularity and a coincidence of all the parts in the very object, which from every other point of view must appear confused and distorted. The spirit of sectarianism has been hitherto our fault, and the cause of our failures. We have imprisoned our own conceptions by the lines, which we have drawn, in order to exclude the conceptions of others. J’ai trouve que la plupart des Sectes ont raison dans une bonne partie de ce qu’elles avancent, mais non pas tant en ce qu’elles nient.
