We have arrived at last at the outwork of the whole matter in its bearings upon life and human duty. It was in the search after this last, that Spinoza, as we said, travelled over so strange a country, and we now expect his conclusions. To discover the true good of man, to direct his actions to such ends as will secure to him real and lasting felicity, and, by a comparison of his powers with the objects offered to them, to ascertain how far they are capable of arriving at these objects, and by what means they can best be trained towards them--is the aim which Spinoza assigns to philosophy. 'Most people,' he adds, 'deride or vilify their nature; it is a better thing to endeavour to understand it; and however extravagant my proceeding may be thought, I propose to analyse the properties of that nature as if it were a mathematical figure.' Mind being, as he conceives himself to have shown, nothing else than the idea corresponding to this or that affection of body, we are not, therefore, to think of it as a faculty, but simply and merely as an act. There is no general power called intellect, any more than there is any general abstract volition, but only _hic et ille intellectus et haec et illa volitio_. Again, by the word Mind is understood not merely an act or acts of will or intellect, but all forms also of consciousness of sensation or emotion. The human body being composed of many small bodies, the mind is similarly composed of many minds, and the unity of body and of mind depends on the relation which the component portions maintain towards each other. This is obviously the case with body; and if we can translate metaphysics into common experience, it is equally the case with mind. There are pleasures of sense and pleasures of intellect; a thousand tastes, tendencies, and inclinations form our mental composition; and since one contradicts another, and each has a tendency to become dominant, it is only in the harmonious equipoise of their several activities, in their due and just subordination, that any unity of action or consistency of feeling is possible. After a masterly analysis of all these tendencies (the most complete by far which has ever been made by any moral philosopher), Spinoza arrives at the principles under which unity and consistency can be obtained as the condition upon which a being so composed can look for any sort of happiness; and these principles, arrived at as they are by a route so different, are the same, and are proposed by Spinoza as being the same, as those of the Christian religion.
