USA [email protected] Abstract Plato in the Meno is standardly interpreted as committed to condition innatism: human beings are born with latent innate states of knowledge. Against this view, Gail Fine has argued for prenatalism: human souls possess knowledge in a disembodied state but lose it upon being embodied. We argue against both views and in favor of content in- natism: human beings are born with innate cognitive contents that can be, but do not exist innately in the soul as, the contents of states of knowledge. Content innatism has strong textual support and constitutes a philosophically interesting theory. Keywords Plato – Meno – innatism – epistēmē – doxa 1 Introduction The question that serves as the title of this paper might seem like one not worth asking. Not because it is uninteresting or philosophically unimportant, but because the answer to it is largely taken to be settled: yes, in the Meno © Koninklijke Brill NV, Leiden, 2019 | doi:10.1163/15685284-12341969 2 Bronstein and Schwab Plato maintains that human beings are innately endowed with knowledge (epistēmē), and what we call ‘learning’ consists in recollecting it. We agree that Plato is an innatist. Nevertheless, we think that this ques- tion deserves to be revisited for two main reasons. First, some interpreters, most notably Gail Fine,1 have recently presented powerful arguments against attributing innatism to Plato, arguing instead that he accepts a view we will call prenatalism: Prenatalism: Human souls possess knowledge in a disembodied state but lose that knowledge upon being embodied. The goal of recol- lection is for the soul to come to know again what it once knew but now no longer knows. Fine’s account raises serious worries for innatist interpretations of the Meno and must be answered. Second, we think that the standard understanding of the kind of innatism that Plato advances in the Meno is mistaken and that getting clear on this en- ables us to examine deep and important philosophical issues. By far the domi- nant view is that Plato thinks the human soul is innately endowed with the cognitive state of knowledge. Such knowledge is often characterized as being ‘implicit’ or ‘latent’ in contrast to knowledge that is ‘explicit’ or ‘conscious’.2 So, on the dominant interpretation, Plato accepts a view we will call condition innatism (adapting Fine’s label ‘cognitive condition innatism’):3 Condition Innatism: Human beings are born in the cognitive condition of knowing, in the sense that human embodied souls pos- sess latent innate states of knowledge. The goal of recol- lection is to make one’s latent knowledge explicit. On the reading we will propose, Plato does not think that human beings are in- nately endowed with states of knowledge but, rather, with truths that can serve as the contents of states of knowledge. Just as there are uncognized truths ‘out there’ in the world that we can grasp via perception, Plato thinks that there are 1 See Fine 1992, 2007 and 2014.

On our reading, then, Plato accepts a view we, following Fine, will call content innatism:4 Content Innatism: Human beings are born with innate cognitive contents, in the sense that human embodied souls innately possess truths that can be the contents of states of knowledge but do not exist innately in the soul as the contents of such states. The goal of recollection is to take up these contents in such a way that one knows them (again). A clarification is in order. Although we have deliberately characterized the three positions as mutually exclusive, there are points of overlap among them. Like prenatalist interpreters of Plato, both condition and content innatist in- terpreters think that, for Plato, the soul, prior to its embodiment, existed in a disembodied state in which it was in the condition of knowing.5 In addition, like content innatist interpreters, condition innatist interpreters think that the soul possesses innate cognitive contents. However, unlike content innatist in- terpreters, condition innatist interpreters think that these are the contents of the soul’s latent innate cognitive states. It is worth underscoring this difference between the two views. Content innatism is the view that there are uncognized truths in the soul. The reason it is appropriate to call these truths ‘cognitive contents’ is that they are the possible contents of the soul’s future occurrent cognitive states (such as opining and knowing). However, they do not exist in the soul as the actual contents of the soul’s present latent cognitive states, as condition innatist interpreters of Plato maintain.6 4 See Fine 2014, 21-2 and 141-2. 5 That is, condition and content interpreters also think that Plato posits prenatal knowledge, but they do not accept prenatalism, as we have defined it, because they do not accept that the soul loses its knowledge (in the form of either cognitive states or contents) upon being embodied. Some philosophers are innatists without accepting any form of prenatal exis- tence (see, perhaps most famously, Leibniz, Discourse on Metaphysics XXVI and, much more recently, Chomsky 1988, 4). 6 For useful discussions of the different varieties of innatism in ancient, early modern and contemporary philosophy, see Barnes 1972, Cowie 1999, 3-26, Fine 2014, 21-3 and 141-6, and Scott 1995, 91-5, 188-90, and 213-16. These authors discuss a third type of innatism—especially in connection with early modern debates—which they call ‘dispositional innatism’. We do not discuss dispositional innatism in this paper for the following reason. As we argue below, the question of the nature of Plato’s innatist commitments in the Meno turns largely on the referents of the terms ‘doxa’ and ‘epistēmē’ at key points in the text. In our view, the most likely candidates for the referents of these terms are either the states of opinion and knowl- edge (respectively) or the contents of these states. Therefore, the two most likely candidates for the form of innatism to which Plato is committed are condition and content innatism.

The structure is as follows: first we briefly survey the central texts over which this debate plays out. The aim of that discussion is to show that there are two prima facie tensions in the Meno. We then look at, and reject, Fine’s attempt to resolve the prima facie tensions, arguing, against her, that we must attribute innatism, and not prenatalism, to Plato. Once we have argued that Plato is an innatist, we spend the bulk of the paper examining what kind of innatist he is. We argue that only a content inn- atist interpretation can resolve the two tensions in a textually and philosophi- cally satisfactory way. 2 The Tensions The main passage in which these issues play out is the famous exchange be- tween Socrates and Meno’s slave.7 After drawing a two-foot-by-two-foot square on the ground, Socrates asks the slave to identify the line on which a square with double the area is based (82b9-e2). The slave eventually arrives at the cor- rect answer: the line is the diagonal of the original square (we will call this ‘the geometrical truth’). Our aim in this section is to argue that, over the course of the exchange, Socrates commits himself to the following three apparently inconsistent claims: P1: The slave does not know the geometrical truth. P2: The slave has innate mere true opinion of the geometrical truth. P3: The slave has innate knowledge of the geometrical truth. (Socrates’ commitment to P2 and P3 is of course disputed by the prenatalist in- terpreter. Our aim in this section is to argue in a preliminary way that Socrates is committed to these claims. We defend innatism against prenatalism in the next section.) Attributing P1 to Socrates is straightforward, as he repeatedly says that the slave does not know the geometrical truth. We offer just two of the clearest We also think that dispositional innatism is vulnerable to an objection similar to the objec- tion we raise below against condition innatism. For further discussion, see n. 38 below. 7 As Irwin 1995, 132 n. 12 notes, the term Socrates uses for Meno’s slave, ‘pais’, can refer to a slave of any age; thus, uses of the expression ‘slave boy’, common in discussions of the Meno, are inappropriate. See Benitez 2016 for a detailed argument to the same effect. doi:10.1163/15685284-12341969 | Phronesis (2019) 1-39 Is Plato an Innatist in the Meno? 5 examples.
