The agnosticism of Kant regarding the noumenon

I’ve never read anyone so difficult to understand as Kant, but his importance serves as a goad to persist… If anyone reading this is a Kantian or a Kant scholar, please feel free to correct me if what I’m saying here is either inaccurate or contested. Anyway, as I quoted in a previous post, Etienne Gilson writes, “Today our only choice is not Kant or Descartes; it is rather Kant or Thomas Aquinas. All the other positions are but halfway houses on the roads which lead either to absolute religious agnosticism or to the natural theology of Christian metaphysics” (God and Philosophy p. 114). In §32 of the Prolegomena, Kant refers to “special beings of the understanding (noumena), which are supposed to constitute an intelligible world.” He grants the possibility of the existence of such beings “but only with the enforcement of this rule that admits of no exception: that we neither know nor can know anything at all determinate about these pure beings of the understanding, because our pure concepts of the understanding as well as our pure intuitions extend to nothing but objects of possible experience” (i.e., extend to the realms of Newtonian physics). Here is Kant’s agnosticism regarding intellectual beings. Kant’s interest is not that we be conformed to the totality of what is real as much as we are able (in conduct and thought) but that we ourselves process our intuitions rendering them into experience which is in accordance with the laws of Newtonian physics (the principles of which reside in us a priori). I would like to contrast what Kant regards as being our own a priori understanding which is able to order our intuitions as coherent experience with Aquinas’ notion (h/t Aristotle) of the “agent intellect” (i.e., the proper active principle). The agent intellect renders intelligible all sensory experience received by the “possible intellect” (i.e., the passive principle). Aquinas’ cognitive theory has the interaction between active and passive principles as foundational to all reality. In Kant there is also an interaction between active and passive principles, but where the natural theology of Aquinas gives us the ability to say something “positive” about the objects external to us, in Kant we have external to us something real but we know not what (“we are not discussing the origin of experience, but what lies in experience” §21a). Kant’s agnosticism regarding “special beings” extends to the very origins of our intuition. While they are ‘real’ we can’t know them. So, there is an activity of some sort, as without it our intuitions receive nothing whatsoever, but his philosophical commitments don’t allow him to express anything confident or positive about what constitutes that activity.

It’s either Thomas Aquinas or Immanuel Kant…

According to Etienne Gilson anyway…

“Today our only choice is not Kant or Descartes; it is rather Kant or Thomas Aquinas. All the other positions are but halfway houses on the roads which lead either to absolute religious agnosticism or to the natural theology of Christian metaphysics” (God and Philosophy, p. 114).

A connection between Locke and Aquinas regarding the limits of human perception and understanding

Locke states, “There is not so contemptible a plant or animal that does not confound the most enlarged understanding” (Essay Concerning Human Understanding Bk III, VI, 9).  Later he says, “how, vain… it is to expect demonstration and certainty in things not capable of it, and refuse assent to very rational propositions… because they cannot be made out so evident as to surmount every… pretense of doubting” (Essay Bk IV, XI, 10). Locke then establishes belief as a way to “supply our want of knowledge.” The grounds for believing which Locke gives, especially the second being “the testimony of others…” has implications regarding the intellectual defensibility of the Christian faith.

Aquinas wrote something regarding how the limits of our powers of perception and understanding ought to not result in skepticism of anything that cannot be demonstrated, especially in relation to the Christian faith. In the Prologue of his exposition of the Apostles’ Creed ( he answers the question “what is faith?” Aquinas says, “But someone will say that it is foolish to believe what is not seen, and that one should not believe in things that he cannot see. I answer by saying that the imperfect nature of our intellect takes away the basis of this difficulty. For if man of himself could in a perfect manner know all things visible and invisible, it would indeed be foolish to believe what he does not see. But our manner of knowing is so weak that no philosopher could perfectly investigate the nature of even one little fly.” Given our limited experience and understanding we must often “partake” in the knowledge of a knower. This involves a humble recognition of the limits of our experience and knowledge, and a willingness to be in a relationship of trust with our fellow human beings who have experience and knowledge which we have not. Ultimately, according to Aquinas and Locke, it must direct us to trust in God and his revelation.

Comparing Thomas Aquinas and Aristotle’s conception of the human good.

Whereas both Thomas and Aristotle would agree that “the ultimate end of man, as of any intellectual substance, is called felicity or happiness” there is a profound difference between them regarding in what that happiness consists. The difference between Thomas and Aristotle’s accounts of the human good boils down to the difference between Thomas’ Christianity (grace and faith) and Aristotle’s virtuous paganism (the integrated intellectual life at its humanly best).

Aquinas studies – happiness is found in an act of the intellect rather than an act of the will.

Thomas agrees with Aristotle regarding in what faculty happiness is found. Aristotle limits the state of happiness to those beings which have the capacity for rational thought. He says, “Happiness is an activity of the [rational] soul” (Aristotle, Nicomachean Ethics, 1100a15). Thomas echoes and expands on this when he says “happiness is the proper good of the intellectual nature” (Thomas Aquinas: Selected Writings, Penguin Books., London 1998, p 268).

Arriving at the link between ‘happiness,’ ‘the proper good,’ and the ‘intellectual nature’ occurs after discounting the various misconceptions regarding what happiness/the proper good are, namely physical pleasure, honour, wealth and any other pursuits which are not ‘self-sufficient’ but rather transitory and contingent. Also, finding happiness in the intellect involves recognizing that the intellect is our highest faculty. As sight is are our highest sensory faculty by which we are able most accurately to perceive the world around us, so our intellects are our highest faculty, enabling us to understand the world around us. Happiness and the proper good are bound up with our telos. It is the intellectual nature which is the specific difference between humans and all other created compound beings (the imago dei), and thus our happiness is to be found in relation to our intellectual nature. Thus, true happiness for us is to be found in intellectual activities directed towards God. “God is the ultimate end of the intellectual substance and that operation whereby a man first attains God is said to be substantially his happiness or felicity” (Aquinas, Selected Writings, p. 270). This ‘attaining’ is some kind of intellectual sight – the Beatific Vision.

Forms and healing come by nature but knowledge from God is “teaching within” – the active and passive principles at play in human life

Forms come by nature. Thomas says, “certain seeds of the sciences pre-exist in us, namely, the first conceptions of the intellect which are known right away by the light of the agent intellect through species abstracted from sensible things” (Thomas Aquinas: Selected Writings, Penguin Books., London 1998, p.198). The pre-existent seeds Thomas is referring to are those images which we passively receive by our senses and naturally actively abstract to some degree by way of our inherent agent intellect. Our agent intellect is created to function commensurately with our senses as it interacts with nature. The agent intellect is the active principle in our intellect that abstracts, or processes, all our sensory data, rendering them to our memories (passive intellect) for further consideration (if we want).

Aquinas studies: if we cannot know the essence of God, how can there be a science of divine things?

The notion that there can be a science of divine things does not negate Thomas’ statements regarding how we are unable to know the essence of God. A science of divine things is possible so long as we are clear regarding what we actually can and cannot know, and how the science of divine things proceeds.

For an excellent introductory guide to Aquinas follow this link.

First of all, only God can know his own essence. In fact, he knows himself “through his essence” (Thomas Aquinas: Selected Writings, Penguin Books., London 1998. p. 116). In other words, only God can truly know himself, as it is his essence to do so. The science of divine things must proceed from this basic understanding, namely, we cannot essentially know God. This does not mean, however, that we cannot in any way come to know God (as we will see).

Secondly, in terms of human reason, according to Thomas we can approach knowledge of God referring to the fact of his existence (and not of what he is). This can be done in three ways: 1) observing his effects in creation; 2) understanding his causality of “more noble effects” which grants a “better display of his eminence”, and; 3) in a negative sense we understand more clearly how he transcends all things and defies definition (Thomas quotes Dionysius, “he is known as the cause, the excess and negation of all things” – (Aquinas, Selected Writings, p. 117).

Boethius’ description of Providence, Fate, and Fortune in Bk IV.

Lady Philosophy asks Boethius to “imagine a set of revolving concentric circles” in her effort to explain how Providence and Fate relate to one another. It is extraordinary how Boethius evokes a visual image to try and explain a deep and perennial mystery. The innermost circle is closest to “the simplicity of the centre” which is equated to the “high citadel of oneness” which is Providence or “Divine Reason.” Providence is also equated to the “Primary Intelligence.” Due to it being equated with Divine Reason, Providence does not itself orbit anything. It does not move. It is essentially the Unmoved Mover. The closer an orbit is to the simplicity of the centre, the more that thing which is the circle is freed from Fate (or “above the chain of Fate”). It seems to me this is essentially “rest”.

Virtue isn’t “natural” it’s a “craft”

In the Nicomachean Ethics Aristotle is considering the question, “What is the highest of all the goods pursued in action” (1095a15)? In order to answer this question, we must begin with things that we know (1095b). He proceeds to answer the question by considering and ruling out what vulgar people and socially cultivated people regard as the highest goods to be pursued. These things are not sufficient for Aristotle, as they are not self-sufficient. They are transitory and fragile. He states that “the best good is apparently something complete” (1096a25) and he understands the best good to be happiness, as this is the thing we aim at in all our activities and investigations. He says, “we regard something as self-sufficient when all by itself it makes a life choiceworthy and lacking nothing; and that is what we think happiness does” (1097b10).

Aristotle’s view of the human good in the Nicomachean Ethics

Aristotle is absolute in stating “Every craft and every investigation, and likewise every action and decision, seems to aim at some good; hence the good has been well described as that at which everything aims” (1094a). However, this does not mean that everything aims at the same ‘goods’. As he says, “there is an apparent difference among the ends aimed at” (1094a). Whereas humanity shares the characteristics of plant and animal life, and whereas the same things which are good for the wellbeing of plants and animals are also good for us (nourishment, health, etc) the good at which we aim is different and greater than the good at which a plant, for example, aims in growing and reproducing. This is because of the specific difference between humans and other living things, plant or animal.

What makes humans unique? What is our function that differentiates our good from other goods? “The human function is the soul’s activity that expresses reason, or requires reason” (1098a5). This expression and requirement of reason is for the human “a certain kind of life” which when completed well expresses “proper virtue” (1098a10). As this is regarded as the right function of the human being, the virtue of living well according to reason is the human good. “The human good turns out to be the soul’s activity that expresses virtue” (1098a15).
