Kant’s third critique, The Critique of Judgment, was published in 1790, two years after the Critique of Practical Reason. Although it did not receive the immediate attention of the previous two critiques—some even dismissed it as the product of senility—its historical impact has been significant. Kant himself looked upon it as the completion of his critical project.
Kant’s first two critiques had left us inhabiting two very different worlds: the deterministic world of nature and knowledge, and the free world of morality. The purpose of the Critique of Judgement was to serve as ‘a bridge between realms’ and help bring these two worlds together.
Hierarchy of the Arts
Kant has much to say about beauty in both art and nature, beginning with the fine arts. He established a hierarchy of the arts based on their capacity to engage the imagination and understanding, and their potential for moral and intellectual improvement and the stimulation of afterthought (Nachdenken). First came the speaking arts of poetry and rhetoric, then the ‘formative arts’ such as painting, sculpture, and architecture, and, finally, the ‘arts of the play of sensations’ such as music. Schopenhauer, by contrast, would place music at the top of the hierarchy.
Nature as a Model
For Kant, nature, which appears purposive (Zweckmäßig) to the human mind, is the model or standard for artistic beauty. An appreciation of natural beauty suggests a moral disposition, whereas even ‘a hardened old usurer’ could take an interest in art—pointing to the pre-eminence of natural beauty. The artist (genius) aims to create art that appears as if it were a product of nature.
The core of aesthetic judgement of both nature and art is the perception of ‘formal purposiveness’, or ‘purposiveness without a purpose’ (Zweckmässigkeit ohne Zweck), which allows for the ‘free play’ of the cognitive faculties and leads to aesthetic pleasure.
When Friedrich Schiller (d. 1805) wrote that a person ‘is only fully human when he is at play’, he was building on Kant. When contemplating beauty, or playing, we temporarily escape the tyranny of practical ends. We engage in something not because it leads to something else, but because it is worthwhile in itself.
The Four Moments of a Pure Aesthetic Judgement
For Kant, a pure aesthetic judgement has four complementary aspects, or ‘moments’, based on the logical functions of judgement: quality, quantity, relation, and modality. These are, respectively, disinterested satisfaction, universal subjectivity, purposiveness without a purpose, and necessary delight.
Disinterestedness: Our satisfaction in beauty must be purely disinterested, that is, without any consideration for instrumentality (for example, the utility of the vase, the worth of the painting), moral significance, or even existence. Our focus ought to be purely on the contemplative experience of the object itself. In other words, we ought to look upon the object, or its beauty, not as a means to an end but as an end in itself. If something merely satisfies or gratifies our appetites, it is agreeable rather than beautiful.
Thus, Canary wine is merely agreeable—unless, it has been argued, we adopt a disinterested attitude towards it, swishing it and spitting it out.
Universal subjectivity: When we call something beautiful, we expect other disinterested, right-thinking people to agree with our judgement, as if beauty were an inherent property of the object. The agreeable, on the other hand, is a ‘private feeling’, and we are not indignant if others do not share our penchant for blue cheese or anchovies. Whereas the judgement of the agreeable is born out of our personal characteristics, the judgement of beauty is disinterested and grounded in cognitive faculties that we have in common with every other human being.
Here again, in his aesthetics as in his morality, is this Kantian notion of the objectivity of intersubjectivity. Judgements of taste are neither purely subjective (based solely on individual pleasure), as Hume believed, nor purely objective (based on a perfect standard in the object itself), as Baumgarten believed. Instead, they are an expression of the free play of the cognitive faculties that all human beings have in common.
Purposiveness without a purpose: Beauty does not reside in an object’s instrumentality. Nor is it an inherent property of the object. Instead, the judgement of beauty arises from the object’s form displaying a ‘purposiveness without a purpose’. The object’s form appears to have been designed with some indeterminate purpose, exhibiting order and harmony. ‘Beauty is a form of purposiveness in an object, so far as this is perceived in it apart from the representation of an end.’
Kant argued, controversially, that the ingénue is at greater liberty to enjoy the beauty of a flower than is the botanist, who gets caught up in the various ends of the flower and its parts. Kant’s philosophy of beauty significantly influenced the development of a movement in art criticism known as formalism, which emphasises compositional elements such as form, colour, and spatial arrangement over content or context.
Necessary delight: The object is the source of necessary pleasure or satisfaction. Even though this pleasure is not an objective property of the object, it is grounded in an a priori principle of the mind, namely, the free play of the cognitive faculties, especially the imagination and understanding. As such, it ought to be universally shared and acknowledged.
The Experience of Beauty
The feeling of beauty, uniquely, bridges the divide between the deterministic world of nature and knowledge and the free world of judgement and morality. In experiencing beauty, we reveal our dual nature: we belong to the phenomenal world of cause and effect, but also to the noumenal world of reason and freedom. Computers, and non-rational beings, do not straddle these two worlds.
But there is another reason why a computer could never experience beauty. A computer might learn which patterns human beings call beautiful. It might recognise a beautiful face, predict our aesthetic preferences, and even generate a poem, picture, or piece of music that moves us. But recognising, predicting, or even producing beauty is not the same as experiencing it.
For Kant, beauty is not simply a property to be detected. It is a feeling that arises from the free play of our cognitive faculties, and from our disinterested contemplation of an object without regard to what it can do for us. A computer is always directed towards an end, and has no opportunity or desire to stop and admire the view.
For Kant, then, beauty gives us a glimpse of a world in which nature and freedom, reality and our highest aspirations, are somehow reconciled. Beauty, in other words, is a vision of heaven on earth—which is why we should value beauty and surround ourselves with beautiful things.
Beauty and beautiful things make the world feel like a better place, a place, finally, that feels like home.
