The analogy between Thought and Extension under the two aspects of necessary connexion and mere contingent relation in co-existence or succession, was, in truth, more interesting to its author as a basis for his ethical than as a development of his metaphysical speculations. The two orders of relations represent, in their distinction, the opposition of science to opinion or imagination, the opposition of dutiful conviction to blind or selfish impulse. Spinoza borrows from the Stoics their identification of volition with belief; but in working out the consequences of this principle it is of Plato rather than of the Stoics that he reminds us. The passions are in his system what sense, imagination, and opinion were in that of the Athenian idealist; and his ethics may almost be called the metaphysics of the Republic turned outside in. Joy, grief and desire are more or less imperfect perceptions of realitya reality not belonging to the external world but to the conscious subject itself.571 When Spinoza traces them to a consciousness or expectation of raised or lowered power, we recognise the influence of Hobbes; but when, here as elsewhere, he identifies power with existence, we detect a return to Greek forms of thought. The great conflict between illusion and reality is fought out once more; only, this time, it is about our own essence that we are first deceived and then enlightened. If the nature and origin of outward things are half revealed, half concealed by sense and imagination, our emotions are in like manner the obscuring and distorting medium through which we apprehend our inmost selves, and whatever adds to or takes away from the plenitude of our existence; and what science is to the one, morality and religion are to the other.
