This essay in 27 letters represents the author's primary philosophical statement, and an entire generation of post-Kantian idealists and early Romantics were heavily influenced by its arguments establishing the cultural, psychological, and, if I may say, soteriological function of art. It is also essential reading for students of Hegel, whose Phenomenology was profoundly influenced by its ideas, method, and terminology.
It is also an awkward and inelegant work, one which shows Schiller to have a poor command of philosophical argumentation. Brilliant insights and calls to action are crowded side-by-side with long, wearying passages that attempt to systematize his thoughts in a way their provisional character cannot support. His ideas are brilliant but underdeveloped, and I think even the most sympathetic modern reader will hesitate to agree that beauty can perform the heavy lifting Schiller requires of it. This is an important aspect of the work that is seldom acknowledged by its critics, and I will return to it later.
In his outstanding study Natural Supernaturalism, M. H. Abrams interprets this essay as belonging to a genre of works presenting a general history of the evolution of humanity's moral, cultural, and intellectual capacities, which also includes Herder's Ideas on the Philosophy of History of Mankind and Kant's Conjectural Origin of the History of Man.
Abrams argues that the primary task of the age in which Schiller wrote was to recover the core insights of the religious and spiritual legacy of European thought and to naturalize it - to recast its mystical and supernatural elements in psychological and philosophical terms. He sees Schiller's core argument as essentially recapitulating the Christian concept of the felix culpa or fortunate fall in secular form. This refers to the idea that humanity's fall in the Garden should be viewed as a blessing, since it prepared the way for our redemption by Christ, which brought us nearer to God. Similarly, Schiller will argue that our fall from innocence will be ultimately redeemed through a higher synthesis of faculties that he interprets as aesthetic in character.
Schiller sees man's original state of nature in explicitly prelapsarian terms. Like Rousseau, he believes that before culture divides humanity's consciousness into differentiated powers that may be developed in different degrees, we existed in a naive and simple state of unity, living unreflectively as a part of nature and compelled to act according to our instincts and natural impulses. Once we developed our intellectual capacities, we were "expelled from the Garden" as it were, alienated from that pre-reflective simplicity. This alienation caused a kind of psychic wound rooted ultimately in the differentiation of our conscious life into different, disjunct domains, such as nature versus culture. In his analysis of this essay, Carl Jung compares this state of fragmentation to the wound of the grail king Amfortas, which cannot be healed by anything less than divine grace.
Schiller divides human experience into two complementary domains: the timeless domain of form and idea, and the temporal world of the finite, transitory objects of sensual experience. I would call this a form of the more general distinction between synchronic and diachronic modes of experience. Or, in Abram's frame, we might characterize this as a secularization of the ancient divide between the material and the spiritual, between body and soul.
In Schiller's view, the human being is likewise divided into a timeless dimension that he calls our personality, which he regards as ensuring the persistence of our character over time, and a temporal dimension that he calls our condition [Zustand], which includes all changing aspects of the self that belong to the temporal world. He awkwardly attempts to link this underdeveloped division to various ideas developed by Kant and Fichte, such as by arguing that our capacity to generate moral laws comes from the strictly timeless dimension of the personality, in obvious deference to Kant's deontology.
Schiller argues that the two aspects of our experience have a corresponding "drive": the "material drive" [Sachtrieb], by which we sensuously engage with the material world, and the "form drive" [Formtrieb] by which we seek to impose a static, lawful regularity on the dynamic flux of our experience. He sees this as a fundamental disjunction in the human psyche occasioned by the rise of abstract reflection, which creates an unbridgeable gulf between these two modes, thereby alienating the rational person from their sensual side.
In a manner that obviously attracted the attention of young Hegel, Schiller argued that there must be a third faculty by which these two disjunct tendencies can be synthesized. He even uses the term "aufheben," or sublimation, to describe the process by which these dichotomous terms can be simultaneously negated and preserved as the system moves up to a higher logical level. This concept became a core part of Hegel's dialectical terminology.
Later in the work, he attempts to reconstruct the general structure of humanity's historical evolution through various modalities of experience. In this context, he introduces another term that will become central in Hegel’s Phenomenology: the idea of moments [Momente] of cultural evolution. This term emphasizes the ambiguity between chronological and logical priority. For example, when he says that the rational mode is a moment that necessarily precede the aesthetic mode, it is intentionally ambiguous if he means that there is a literal historical sequence that must be followed, or if rationality as such is necessarily prior to the aesthetic mode in a logical sense, and is somehow subsumed by it. This is an interesting and suggestive flattening of ideas, but it does not exactly serve the cause of clarity.
The synthesizing drive that Schiller believes unites the other two is the play drive [Spieltrieb], and in what becomes one of the most famous aspects of this essay, Schiller sets about to rehabilitate our notion of play. He understands the idea in its most expansive sense, as a immediately-gratifying condition of life resulting from excess and overflow, in which individuals are free to create, not mechanically compelled by instinct or by formal law, as we would in the state of nature or in a mode of mere rational reflection, but in a higher mode that encompasses both states of being.
Each of these drives has a corresponding object: the object of the Sachtrieb is life, the object of the Formtrieb is the abstract concept or law, and the object of the Spieltrieb is beauty.
Beauty, in conjunction with the human capacity to play, becomes a synthesizing (i.e., redemptive) power that reunites the shards of our being in a way that elevates our nature. It becomes a force by which we are positively motivated by the attractive power of beauty and move toward it according to our will, not compelled by our appetites or the force of a moral command. In this sense, Schiller binds the idea of beauty to the idea of freedom, and concludes the work by arguing that truly free modes of human interaction are made possible by beauty and play:
"The aesthetic formative impulse establishes insensibly a third joyous empire of play and of appearance, between the formidable realm of powers and the sacred realm of law — an empire wherein man is released from the binds of circumstance, and is freed, both physically and morally, from all that can be called constraint."
On one level, this essay is a social argument for the values of beauty and play, seeking to establish their importance in the grand scheme of human endeavor. In one of its most frequently-cited lines, Schiller tells us that man is always most nearly himself when he plays.
Beauty should generally be understood as a powerful response to a beautiful work of fine art or person. For Schiller, a deep experience of beauty is a profound and transformative experience that would seem to be modeled on the beatific vision. it is a moment when time and space seems to fall away, when ultimate value is directly communicated to the receptive psyche. Drawing from James Joyce, Joseph Campbell called this kind of experience as one of "aesthetic arrest."
In this sense, it's easy to tie Schiller's core argument to Abrams's reading of the work as essentially a secularization of various millennialist and soteriological arguments that are ready-to-hand. Both the individual divided consciousness and the temporal world are redeemed by the aesthetic insight, and art becomes the new vehicle of salvation. This argument was profoundly influential on the Romantics and indeed, on all of nineteenth-century German thought. Schiller was not the first or only person to characterize art as the new sacrament, as the new and primary sphere of ultimate value for humanity, but he was certainly one of the most important and influential.
And, for Hegel and a generation of early Romantics, Schiller's association of all this with a political concept of freedom inspired by Rousseau and by the early promise of the French Revolution would be no less influential. Schiller's personal concern for freedom stems from his experience growing up in the hereditary duchy of Württemberg, where the duke wielded absolute power. He spent long, miserable years in an oppressive military academy and then served as an army doctor and, after the dramatic success of his first play Die Räuber, he was imprisoned by the duke and forbidden to write further plays. He eventually illegally fled the duchy and resettled in Jena, near Weimar.
So it must be remembered that for Schiller, “freedom” was not a romantic notion or a mere political slogan, and one can easily understand why he associated it with both an overflowing abundance of life and with artistic creativity.
When you lay out the argument like this, it is easy to see why it was so influential and important. However, as I alluded to above, this work is terribly written. Goethe himself complained to Eckermann that "The more [the Germans] give themselves up to certain philosophical schools, the worse they write ... in this sense, Schiller's style is at its most magnificent and effective whenever he doesn't philosophize...."
["Je näher [die Deutschen] sich gewissen philosophischen Schulen hingegeben, desto schlechter schreiben sie.... So ist Schillers Styl am prächtigsten und wirksamsten, sobald er nicht philosophiert...."]
As a philosopher, Schiller was strictly an amateur, and he probably would have been well advised to present his ideas as a philosophical essay in the manner of Herder rather than attempting to ape the systematicity of Kant and Fichte. We can accept the general idea of dividing human experience into a temporal and atemporal dimension, for example, without believing that there is really something "eternal" that shapes human personality, or worse, that such a notion is necessary to account for the persistence of the human personality over time. This argument is based on Fichte's Ich-philosophy but receives no explanation or support, and in Schiller's hands it reads like something a sophomore philosophy major would claim. Does the table also possess an eternal personality, since it remains a table?
As a simplified construction, there is nothing wrong with speaking in this way, but again and again, Schiller treats these constructs like they can be rigorously elaborated, and it does nothing more than emphasize their inadequacy. The essay is crowded with many such arguments, passages that I came to call "garbage talk" in my marginal notes, such as the following example from the twenty-fifth letter:
"In our satisfaction at cognitions we distinguish without trouble the passage from activity to passivity, and actually observe that the first is over, when the latter appears. On the contrary, in our delight at beauty no such succession between activity and passivity can be distinguished, and reflection is here so thoroughly blended with feeling, that we think the form is directly perceivable. Beauty then is indeed object for us, since reflection is the condition by which we perceive it; but at the same time it is a condition of our subject, because feeling is the condition by which we have a conception of it."
This is simply a word salad of vague and underdetermined concepts.
Most secondary summaries of this text suggest it possesses a strength of argument that it altogether lacks. I believe some commentators don't wish to call out its inadequacies because they fear it is their own lack of familiarity with philosophy that makes it so difficult. But the problem is Schiller, not them, and anyone who compares five pages of this essay with five pages from Schopenhauer will immediately see what I mean.
So let it be said, this text is badly written. It is overly florid and verbose, and the argument is segmented and scattered in ways that make it laborious to track. M. H. Abrams charitably called it "surprisingly intricate." It is also an extremely important work in the history of ideas, and an absolutely key reference for understanding early Romantic and Hegelian philosophy.
