The systematic character of philosophy, understood logically, belongs to every single philosophical proposition which is always a philosophical cosmos, as every drop of water is the ocean, indeed, the whole world, contracted into that drop of water. It is hardly necessary to distinguish from this the _literary sense_ of system, which is the name given to certain forms of exposition, which embrace definite groups of problems, traditionally held to be those in which philosophy is contained. When some or many of those groups do not receive explicit literary treatment, it is said that system is wanting. It is true that there is wanting the fulfilment of a literary task (or what here amounts to the same thing, of a pedagogic task); but the system is there, even in the case when a very specialized problem is treated, provided it be approached with philosophic and so with systematic energy. That the same thinker, when he passes to another problem, should give a wrong solution contradictory to that previously given, does not prove that he had not at first a system, but that he has lost it when faced with the new difficulty. He was at first a philosopher and so systematic; afterwards, not philosopher enough, and so not sufficiently systematic. [Sidenote: _Advantages and disadvantages of the literary form of system._] The traditional groupings of problems, and the construction of system in the literary and pedagogic sense, certainly have their utility (all that exists has its proper function and value). They preserve and promote culture already acquired, by obliging it to examine difficulties, which, were they neglected, might unexpectedly become a great hindrance and loss. Hence the love for system, or for the literary form of system, a love which the author of these pages also nourishes in his soul and of which he has sought to give some proof, by writing a _system,_ although it is long since systems have been written, in Italy at least (unless scholastic manuals be thus called), and it is no slight merit to have braved the ridicule of the enterprise. But systems have also the disadvantage of sometimes leading to a tiresome re-exposition of problems that are out of date and whose solutions have passed into the common patrimony of culture. The treatment of these problems is better left to be understood, that time and space may be gained for the treatment of others more urgent. Hence the rebellion against system, or against the pedantry which can adhere to that form of exposition. This rebellion is similar at all points with that against the pedantry of definition, which is a legitimate rebellion, yet cannot eliminate the logical form of definition. Instead of systems, we write monographs, essays, and aphorisms, but these, if philosophic, will always be inwardly systematic.
