Berkeley on the Meaning of Idea



Berkeley on the Meaning of IdeaStephen H. DanielPhil 412.900January 19, 2014Berkeley on the Meaning of IdeaStephen H. DanielIntroductionThere is probably no issue more debated in Berkeley scholarship than what he means by “idea”. This is understandable, considering how he treats the immediate objects of our perception (i.e., ideas) as the things that comprise the real world. Of course, most of his contemporaries and many later critics are puzzled by this way of speaking about ideas because it seems to ignore how ideas and their objects are ontologically distinct. As is well-known, though, the early 18th century Irish philosopher George Berkeley rejects such a distinction by arguing that it is impossible to conceive of a sensible thing or object apart from the sensation or perception of it (PHK 5, D 230). This allows him, as Michael Ayers remarks, to use “ideas,” “sensations,” “sensible qualities,” “sensible things,” and “sensible objects” more or less interchangeably. “Call them which you will,” Berkeley quips. (D 197, 215)No doubt part of the difficulty here stems from how Berkeley takes advantage of ambiguities in the use of terms such as idea and perception. To get around this, some commentators adopt an act–object model and describe Berkeleyan ideas simply as the objects of our acts of perceiving or thinking. Others rely on the Cartesian distinction between formal and objective reality to explain how ideas exist formally but not objectively in the mind. Worried, however, that this strategy might allow for talk of real things outside of mind, still other commentators prefer to think of ideas as intentional objects. Yet others propose an “adverbial” account, in which ideas are not objects of perception at all but are rather ways of perceiving. But because the adverbial account does not seem to seperate the activity of perceiving from the thing percieved by such activity, still others suggest that we focus, on the one hand, on how mental acts differ from mental events rather than, on the other, on how mental acts differ from mental objects.With such a variety of interpretations, it is no wonder that we have yet to get a good grasp of this principal feature of Berkeley’s philosophy. The purpose of my discussion is to indicate how by reading Berkeley’s published works (in particular, the Principles and the Dialogues) through the lens of his early manuscript Notebooks, we get a clearer view of his doctrine of ideas—specifically, what he means by saying that qualities are in the mind “by way of idea.” I do not assume that the published works mark advances beyond his seperate earlier views. Instead, I contend that some of Berkeley’s published remarks are complicated by his attempts to accommodate his own insights to Cartesian or Lockean ways of speaking that treat qualities (as Berkeley puts it) “by way of mode or attribute.” I conclude that by focusing on the Notebooks we retrieve the key for understanding why he thinks of real things as ideas by clarifying what he means by saying that ideas are “in” (i.e., related to) mind.I. “By Way of Idea”Though commentators might not agree on what ideas are for Berkeley, they generally agree on what ideas are not. For example, ideas are not modes, attributes, qualities, or properties of substances, because that would imply that minds (“spiritual substances”) are extended or colored whenever they entertain such ideas. Instead, he maintains that qualities are “. . . in the mind only as they are perceived by it—that is, not by way of mode or attribute, but only by way of idea” (Principles 49). What “by way of idea” means is clarified (somewhat) in the Dialogues when he observes that “sensible qualities are objects immediately perceived . . . [which] exist, not by way of mode or property, but as a thing perceived in that which perceives it” (D 237). Qualities or objects are thus sensable only if they are specifically identified as those qualities or objects. That is, apart from their being identified “by way of idea” (i.e., “in” the mind), qualities or objects are unintelligible because they have no specific identity. That is why a sensable quality is an object of mind that exists only in mind, namely, as an idea (PHK 89).Berkeley’s remarks on this point lead Andrew Baxter (in 1733), and later Thomas Reid, G.E. Moore and others, to conclude that, for Berkeley, there is no difference between an act of perception and the thing perceived. Indeed, in the first edition of the Principles, Berkeley seems to say just that: “In truth the object and the sensation are the same thing, and cannot therefore be abstracted from each other.” The perception and the thing that the perception is a perception of are the same, for a perception is this or that perception precisely in virtue of it’s object. Furthermore, no object can be imagined that is ontologically distinct from its sensation or perception, for it is by means of that sensation, perception, or idea that the object is identified as that object.We can, however, retrieve some of the context in which Berkeley originally formulates his doctrine of how ideas and minds are related by consulting the Notebooks. There Berkeley indicates how issues relating to what he means by idea are resolved only by recognizing how spirits or minds are not objects of thought (i.e., ideas) but are rather the activity whereby ideas are identified and thought in relation to one another. In the Principles and Dialogues Berkeley seems, at least at first glance, to treat minds as if they were objects by referring to them as “spiritual substances.” But, he says, minds are not objects because they are not ideas nor are they known “by way of idea”:There can be no idea formed of a soul or spirit: for all ideas whatever, being passive and inert . . . they cannot represent unto us, by way of image or likeness, that which acts. . . . So far as I can see, the words will, soul, spirit, do not stand for different ideas, or, in truth, for any idea at all, but for something which is very different from ideas, and which, being an agent, cannot be like unto, or represented by, any idea whatsoever . . . (Pr. 27, also see Pr. 135-42; D 233).If they are not ideas—that is, if they cannot be objects of thought—they cannot be substances in any Aristotelian, Scholastic, Cartesian, or Lockean sense. So when Berkeley says minds are substances, he must therefore mean it when, as he often says, minds are not related to their ideas as supports nor are they places in which ideas inhere (Principles 49, 73-74, 89; Dialogues 212, 237, 249). Rather, the “substance” of mind is simply the consciousness of ideas as determinate, real things.Just as this way of understanding mind requires a different understanding of substance, so it also requires a different understanding of idea. As Berkeley’s contemporaries would have known, this other understanding draws more explicitly on how the expression “by way of idea” means a communication from God. Such a communication cannot be from God to independantly existing minds, for that would imply that our minds are objects (at least as far as God is concerned). So instead of saying that our minds (like other things) exist, Berkeley is generally careful to say that our minds “subsist”—that is, as the particular cognitive and affective arrangements and associations that identify the infinate furniture of the world (NB 109).Within that mindset, we are said to know a sensible object “by way of idea”—or have an idea of a thing—when we place it in relation to other things in our experience (NB 369). This is what it means for something to become an object of thought (NB 808). An act of mind is the perceiving that there be an object, not that there is an object (as if the object exists prior to its being perceived). In perceiving, the mind does not make a judgement about an object (e.g., that a cherry is red), for that would imply that the terms of the judgement (cherry, red) are already determinate and intelligible. Instead, the preception of an idea is an event in which ideas or objects are identified as meaningful by being differentiated. The characterization of a cherry as red is not, therefore, a judgement about the cherry (as if “cherry” could be intelligible apart from its color). In other words, the idea cherry is not a proposition, nor (as George Pappas argues persuasively in his book Berkeley’s Thought) is anything predicated of anything else in the idea cherry. Nonetheless, my having the idea cherry is an expression of God’s will that there be a differentiation of determinate objects in my experience. This event of perceiving is not a judgment, but it expresses a proposition, namely, that there is (in virtue of this event) a differentiation that heretofore has not existed. We can, of course, later describe positing an idea in propositional terms (i.e., as a particular act of will responsible for a particular, seperate idea), but that is done only retroactively.II. The Activity of the MindFor Berkeley, to say that no object can exist apart from its being perceived means that it cannot exist apart from its being willed to be perceived as that thing. The will that there be differentiation among objects does not exist apart from its differentiation in effects. Only in its effects can we discern the identities of things as differences in our affective apprehensions (i.e., as volitions) (NB 808). Volitions are the actions by which each idea is situated as causally related to other ideas (NB 831). The actions by which ideas are identified are thus themselves said to “exist” in only a derivative fashion (NB 644, 673). Though volitions and the will are not ideas—and thus literally do not exist (NB 792)—they are real things (NB 806-807).This leads Berkeley to conclude that the mind is not a thing that perceives (NB 581) but is rather a particular congeries or concrescence of preceptions (NB 580). This does not mean that the mind is a bundle of already differentiated ideas (as David Hume argues); rather, it is the “principle” or activity of differentiation and association by means of which ideas are identified. That is why there is no mind apart from the activity of perceiving, willing, etc. certain specified ideas: when there is no succession of ideas (i.e., no thinking), there is no mind (NB 651).Nonetheless, the mind and its ideas are different, in the same way that the activity of distinguishing and associating ideas is different from the objects distinguished or associated (“bundled”). The activity by which ideas are identified and related to one another is radically different from the objects (ideas) that are bundled. Since the identification of ideas as distinct objects occurs through acts of their being associated in relation to one another (which, by the way, is the means by which we note the passage of time), ideas are said to exist “in” minds, in that they are identified, differentiated, and related to one another by means of an “active principal.” But the principal itself cannot be imagined apart from it’s activity (e.g., thinking, willing) without making it into an object, that is, to treat it as an idea. To say, then, that minds are spiritual substances means that they “support” such identification, differentiation, and relation by being (as Berkeley puts it) the “being” or “existence” of ideas. To have an idea, then, is to think it as an element in a complex of perceiving, willing activity (NB 25, 154, 230). Abstracted from its integral and affective relation with other ideas in that inate complex of cognitive, affective activity, an idea would be a passive sensation whose connections to other ideas is unknown and therefore is considered as having an external cause (NB 286, 499, 744, 756). But from Berkeley’s perspective, it would be inappropriate to imagine such disconnected ideas or to think that souls, persons, or human beings could be mere bundles of ideas.Every agent or self is differentiated and identifiable in virtue of its volitions and ideas. When the self is not willing or thinking, it does not exist (NB 83, 646, 674, 791). So long as I exist or will, I must have ideas (NB 842; Pr. 98). Since no agent can will without willing something, every volition must be informed by a perception: in other words, there is no blind agency (NB 812). Just as volitions are the affective expressions of mind, so ideas are the cognitive expressions of mind. Ideas are thus the products of volitions, volitions are the relations of ideas, and thoughts are ideas that are related to one another volitionally.Concluding RemarksFor Berkeley, then, ideas are intelligible only insofar as they are cognized by mind. To understand what that means requires that we understand what it means for something to be known “by way of idea”. That, in turn, requires that we understand how mind is the means by which we understand ideas. I have suggested that to do that we focus on the Notebooks rather than the Principles and Dialogues. In the Notebooks we discover a way to think about ideas in terms of mind that current interpretations of Berkeley’s doctrine of ideas by and large overlook. Efforts to describe an idea using the act–object distinction—even as qualified in formal–objective, intentionality, or adverbial accounts—or using the mental act–mental event distinction do not capture Berkeley’s central insight about how ideas or sensible objects are initially identified by being differentiated. That is, such views overlook his point that existence is not simply added onto the thing as if it could have an identity apart from its place within a cognitive–affective matrix that designates a mind. Rather, a thing’s very being consists in its being perceived as that thing; and its being that thing consists in its being perceived as that thing by a particular mind. So to describe an idea as a mental event does really not help us, because one of the issues regarding ideas is what it means to call them objects of mind in the first place.Nonetheless, the distinction between act and event is useful because it helps us see how ideas are the identities produced in and through events of differentiation. The act-event distinction also opens up the possibility for thinking that the differentiation of things by or in mind need not be understood in terms of discrete acts by individual minds. For if ideas are identified simply in virtue of their being uniquely perceived by a particular mind, then it is not enough to say that minds themselves are individuated in the first place by God. For then God’s individuality itself needs to be explained. Berkeley helps us avoid such an endless regress, though, by describing ideas as products of differentiating events, not objects created by the discrete acts of a previously individuated being (God).Due to space limitations, I have not been able to pursue other topics that are of even more interest to me than what Berkeley means by ideas. But since all of Berkeley’s doctrines are ultimately grounded on the nature of ideas, my having addressed this topic has to be the starting point for understanding his philosophy and for seeing his importance in the context of other early modern thinkers. ................
