The theory itself, and the whole question regarding the nature of Freedom, can be better understood if we view them in connection with a general truth, which I think, is most concisely expressed by a formula frequently occurring in the scholastic writings: Operari sequitur esse.[2] In other words, everything in the world operates in accordance with what it is, in accordance with its inherent nature, in which, consequently, all its modes of expression are already contained potentially, while actually they are manifested when elicited by external causes; so that external causes are the means whereby the essential constitution of the thing is revealed. And the modes of expression so resulting form the empirical character; whereas its hidden, ultimate basis, which is inaccessible to experience, is the intelligible character, that is, the real nature per se of the particular thing in question. Man forms no exception to the rest of nature; he too has a changeless character, which, however, is strictly individual and different in each case. This character is of course empirical as far as we can grasp it, and therefore only phaenomenal; while the intelligible character is whatever may be the real nature in itself of the person. His actions one and all, being, as regards their external constitution, determined by motives, can never be shaped otherwise than in accordance with the unchangeable individual character. As a man is, so he his bound to act. Hence for a given person in every single case, there is absolutely only one way of acting possible: Operari sequitur esse[3] Freedom belongs only to the intelligible character, not to the empirical. The operari (conduct) of a given individual is necessarily determined externally by motives, internally by his character; therefore everything that he does necessarily takes place. But in his esse (i.e., in what he is), there, we find Freedom. He might have been something different; and guilt or merit attaches to that which he is. All that he does follows from what he is, as a mere corollary. Through Kant's doctrine we are freed from the primary error of connecting Necessity with esse (what one is), and Freedom with operari (what one does); we become aware that this is a misplacement of terms, and that exactly the inverse arrangement is the true one. Hence it is clear that the moral responsibility of a man, while it, first of all, and obviously, of course, touches what he does, yet at bottom touches what he is; because, what he is being the original datum, his conduct, as motives arise, could never take any other course than that which it actually does take. But, however strict be the necessity, whereby, in the individual, acts are elicited by motives, it yet never occurs to anybody—not even to him who is convinced of this necessity—to exonerate himself on that account, and cast the blame on the motives; for he knows well enough that, objectively considered, any given circumstance, and its causes, perfectly admitted quite a different, indeed, a directly opposite course of action; nay, that such a course would actually have taken place, if only he had been a different person. That he is precisely such a one as his conduct proclaims him to be, and no other—this it is for which he feels himself responsible; in his esse (what he is) lies the vulnerable place, where the sting of conscience penetrates. For Conscience is nothing but acquaintance with one's own self—an acquaintance that arises out of one's actual mode of conduct, and which becomes ever more intimate. So that it is the esse (what one is) which in reality is accused by conscience, while the operari (what one does) supplies the incriminating evidence. Since we are only conscious of Freedom through the sense of responsibility; therefore where the latter lies the former must also be; in the esse (in one's being). It is the operari (what one does) that is subject to necessity. But we can only get to know ourselves, as well as others empirically; we have no a priori knowledge of our character. Certainly our natural tendency is to cherish a very high opinion of it, because the maxim: Quisque praesumitur bonus, donec probetur contrarium (every one is presumed to be good, until the contrary is proved), is perhaps even more true of the inner court of justice than of the world's tribunals.
NOTE.
He who is capable of recognising the essential part of a thought, though clothed in a dress very different from what he is familiar with, will see, as I do, that this Kantian doctrine of the intelligible and empirical character is a piece of insight already possessed by Plato. The difference is, that with Kant it is sublimated to an abstract clearness; with Plato it is treated mythically, and connected with metempsychosis, because, as he did not perceive the ideality of Time, he could only represent it under a temporal form. The identity of the one doctrine with the other becomes exceedingly plain, if we read the explanation and illustration of the Platonic myth, which Porphyrius has given with such clear exactitude, that its agreement with the abstract language of Kant comes out unmistakably. In the second book of his Eclogues, chap. 8, §§ 37-40,[4] Stobaeus has preserved for us in extenso that part of one of Porphyrius' lost writings which specially comments on the myth in question, as Plato gives it in the second half of the tenth book of the Republic.[5] The whole section is eminently worth reading. As a specimen I shall quote the short § 39, in the hope of inducing any one who cares for these things to study Stobaeus for himself. It will then immediately become apparent that this Platonic myth is nothing less than an allegory of the profound truth which Kant stated in its abstract purity, as the doctrine of the intelligible and empirical character, and consequently that the latter had been reached, in its essentials, by Plato thousands of years ago. Indeed, this view seems to go back much further still, for Porphyrins is of opinion that Plato took it from the Egyptians. Certainly we already find the same theory in the Brahmanical doctrine of metempsychosis, and it is from this Indian source that the Egyptian priests, in all probability, derived their wisdom. § 39 is as follows:—
Τὸ γὰρ ὅλον βούλημα τοιοῡτ' ἔοικεν εἶναι τὸ τοῡ Πλάτωνος ἔχειν μὲν τὸ αὐτεξουσιον τὰς ψυχὰς, πρὶν εἰς σώματα καὶ βίους διαϕέρους ἐμπεσεῖν, εἰς τὸ ἢ τοῡτoν τὸν βίον ἕλεσθαι, ἢ ἄλλον, ὅν, μετὰ ποιᾱς ζωῆς καὶ σώματος οἰκείον τῇ ζωῇ, κτέλεσειν μέλλει (καὶ γὰρ λέοντος βίον ἐπ' αὐτῇ εἶνai ἔλεσθαι, καὶ ἀνδρὸς). Kakeῑνο μέντοι τὸ αὐτeξoύσιον, ἅμα τῇ πρός τινα τῶν τοιούτων βίων πτώσει, ἐμπεπόδισται. Κατελθοῡσαι γὰρ εἰς τὰ σώματα, καὶ ἀντὶ ψυχῶν aπολυτῶν γεγονῑυαι ψυχαὶ ζώων, τὸ αὐτεξούσιον ϕέρουσιν οἰκείον τῇ τοῡ ζώον κατασκευῇ, καὶ ἐϕ' ὧν μὲν εἶνai πολύνουν καὶ πολυκίνητον, ὡς ἐπ' ἀνθρώπον, ἐϕ' ὡν δὲ λυγοκίνηττον καὶ μονότροπον, ὡς ἐπὶ τῶν ἄλλον σχεδὸν πάντων ζώων. Ήρτῆσθαι δὲ τὸ αὐτeξoύσιον τοῡτo ἀπὸ τῆς κατασκετῆς, κινούμενον μὲν ἐξ αὐτοῡ, ϕερόμενον δὲ κατὰ τὰς ἐκ τῆς κατασκευῇς γυγνομένας προθυμίας.[6]
