Tim Mehigan on ‘Empiricism vs Rationalism: Kant, Reinhold, and Tennemann’
Tim Mehigan writes…
Alberto Vanzo presented two papers for discussion at the recent Otago symposium on early modern experimental philosophy. There are two conclusions in the first paper (“Experimental Philosophy in Eighteenth Century Germany” [on which we’ll publish Eric Watkins’ comments next Monday]) that are important for the second paper: one, that experimental philosophy, as “observational philosophy”, was replaced in German historiography by the term “empiricism” (this occurred sometime before 1796 as a passage from an essay by Christian Garve indicates); two, as experimental/observational philosophy waned, so the historiographical distinction between rationalism and empiricism (RED) waxed. While the reasons for the waxing are not completely clear, there appear to be two ways of imagining how it occurred. The first view holds that Kant himself was responsible for legislating the RED into existence. The second argues that the distinction was not authorized by Kant but arose as a result of the way his philosophy was interpreted and explained by later Kantians such as Reinhold and Tennemann. Both explanations are considered and evaluated in Vanzo’s second paper “Empiricism vs. Rationalism.”
So this is what’s at stake: Vanzo needs to show how the RED can be read into Kant’s first Critique, even if it is not expressly established as a formal distinction on which other parts of the CPR depend. Given the strategy alluded to above – that Kant introduces a distinction under the guise of different terminology – Vanzo is obliged to consider whether we encounter a “mapping” problem when Kant’s contrasts are seen in the context of the RED. He immediately concedes that there is indeed such a mapping problem (as Gary Banham had noted here). The RED is introduced in two places in the CPR – the Antinomies of Pure Reason and the History of Pure Reason. In the first case, Kant contrasts empiricism with dogmatism (not rationalism), and in the second case, Kant contrasts empiricism with “noologism” (not rationalism). The question is: whether RED can “map onto” either or both of these contrasts and thus indicate compellingly that Kant operated with the RED in mind?
As it turns out, the occurrence of the RED in the History of Pure Reason is more readily answered than in the Antinomies. Vanzo establishes both that the contrast of “empiricism” and “noologism” in the History of Pure Reason can be regarded as a version of the RED and that the contrast established here was to become a standard part of the histories of early modern philosophy. The argument in the Antinomies follows a more circuitous route. Vanzo cannot directly show that “dogmatism” and “rationalism” are interchangeable terms, all the more so since Kant’s purpose in the Antinomies is to show that neither dogmatism nor empiricism on its own is able to offer satisfactory proofs of key statements about the world. So both dogmatism and empiricism come up short, and Kant, as a later self-identifying rationalist, is clearly not about to subscribe to the dogmatic variant of metaphysical rationalism. So a problem of mapping does appear here, and it is the more serious one for the RED distinction.
Was the RED introduced by Kant? Vanzo’s final answer is, “not really”. Kant does not have the “epistemological bias” in regard to the RED, i.e. he does not overestimate the importance of the RED on epistemological grounds. Neither does Kant have the “Kantian bias”, according to which the RED is important for his project in the Critique of Pure Reason. Kant, finally, does not have the “classificatory bias” which classifies all philosophers prior to Kant into either empiricist or rationalist camps. When we consider the later Kantians, the picture is quite different. Both Reinhold and Tennemann are said to have the epistemological, the Kantian and the classificatory biases. Reinhold, I believe, did not initially have the classificatory bias, as it is not clearly in evidence in his first major work, the Essay on a New Theory of the Human Capacity for Representation (1789). By the early 1790s, however, as Vanzo shows, Reinhold appears to have derived a historiographical framework based on the RED. Reinhold’s framework appears to have been important for philosophers such as Tennemann, who by the late 1790s had begun to craft a “methodologically sophisticated history of early modern philosophy” in which the RED is amply applied to individual philosophers and where Kant takes his place as the author who successfully overcame the limits of these two schools.
In sum, Vanzo’s case for the establishment of the RED in Germany appears to ascribe great importance to the manner in which Kantian philosophy was received from the mid 1780s until the mid 1790s and how it was laid out against a background of historiographical assumptions. As happens so often, the background was to become foreground for a few brief years, and when it did so under Reinhold’s pen – this is the likely conclusion – the historiography became more important than the philosophy. Fortunately this situation has reversed itself and Kant’s philosophy has become a far more open proposition than it was taken to be in those years. This openness, in turn, makes room for different conceptualizations of the early modern period.
From Experimental Philosophy to Empiricism: 20 Theses for Discussion
Before our recent symposium, we decided to imitate our early modern heroes by preparing a set of queries or articles of inquiry. They are a list of 20 claims that we are sharing with you below. They summarize what we take to be our main claims and findings so far in our study of early modern experimental philosophy and the genesis of empiricism.
After many posts on rather specific points, hopefully our 20 theses will give you an idea of the big picture within which all the topics we blog about fit together, from Baconian natural histories and optical experiments to moral inquiries or long-forgotten historians of philosophy.
Most importantly, we’d love to hear your thoughts! Do you find any of our claims unconvincing, inaccurate, or plainly wrong? Do let us know in the comments!
Is there some important piece of evidence that you’d like to point our attention to? Please get in touch!
Are you working on any of these areas and you’d like to share your thoughts? We’d like to hear from you (our contacts are listed here).
Would you like to know more on some of our 20 claims? Please tell us, we might write a post on that (or see if there’s anything hidden in the archives that may satisfy your curiosity).
Here are our articles, divided into six handy categories:
General
1. The distinction between experimental and speculative philosophy (ESD) provided the most widespread terms of reference for philosophy from the 1660s until Kant.
2. The ESD emerged in England in the late 1650s, and while a practical/speculative distinction in philosophy can be traced back to Aristotle, the ESD cannot be found in the late Renaissance or the early seventeenth century.
3. The main way in which the experimental philosophy was practised from the 1660s until the 1690s was according to the Baconian method of natural history.
4. The Baconian method of natural history fell into serious decline in the 1690s and is all but absent in the eighteenth century. The Baconian method of natural history was superseded by an approach to natural philosophy that emulated Newton’s mathematical experimental philosophy.
Newton
5. The ESD is operative in Newton’s early optical papers.
6. In his early optical papers, Newton’s use of queries represents both a Baconian influence and (conversely) a break with Baconian experimental philosophy.
7. While Newton’s anti-hypothetical stance was typical of Fellows of the early Royal Society and consistent with their methodology, his mathematisation of optics and claims to absolute certainty were not.
8. The development of Newton’s method from 1672 to 1687 appears to display a shift in emphasis from experiment to mathematics.
Scotland
9. Unlike natural philosophy, where a Baconian methodology was supplanted by a Newtonian one, moral philosophers borrowed their methods from both traditions. This is revealed in the range of different approaches to moral philosophy in the Scottish Enlightenment, approaches that were all unified under the banner of experimental philosophy.
10. Two distinctive features of the texts on moral philosophy in the Scottish Enlightenment are: first, the appeal to the experimental method; and second, the explicit rejection of conjectures and unfounded hypotheses.
11. Experimental philosophy provided learned societies (like the Aberdeen Philosophical Society and the Philosophical Society of Edinburgh) with an approach to knowledge that placed an emphasis on the practical outcomes of science.
France
12. The ESD is prominent in the methodological writings of the French philosophes associated with Diderot’s Encyclopédie project, including the writings of Condillac, d’Alembert, Helvétius and Diderot himself.
Germany
13. German philosophers in the first decades of the eighteenth century knew the main works of British experimental philosophers, including Boyle, Hooke, other members of the Royal Society, Locke, Newton, and the Newtonians.
14. Christian Wolff emphasized the importance of experiments and placed limitations on the use of hypotheses. Yet unlike British experimental philosophers, Wolff held that data collection and theory building are simultaneous and interdependent and he stressed the importance of a priori principles for natural philosophy.
15. Most German philosophers between 1770 and 1790 regarded themselves as experimental philosophers (in their terms, “observational philosophers”). They regarded experimental philosophy as a tradition initiated by Bacon, extended to the study of the mind by Locke, and developed by Hume and Reid.
16. Friends and foes of Kantian and post-Kantian philosophies in the 1780s and 1790s saw them as examples of speculative philosophy, in competition with the experimental tradition.
From Experimental Philosophy to Empiricism
17. Kant coined the now-standard epistemological definitions of empiricism and rationalism, but he did not regard them as purely epistemological positions. He saw them as comprehensive philosophical options, with a core rooted in epistemology and philosophy of mind and consequences for natural philosophy, metaphysics, and ethics.
18. Karl Leonhard Reinhold was the first philosopher to outline a schema for the interpretation of early modern philosophy based (a) on the opposition between Lockean empiricism (leading to Humean scepticism) and Leibnizian rationalism, and (b) Kant’s Critical synthesis of empiricism and rationalism.
19. Wilhelm Gottlieb Tennemann was the first historian to craft a detailed, historically accurate, and methodologically sophisticated history of early modern philosophy based on Reinhold’s schema. [Possibly with the exception of Johann Gottlieb Buhle.]
20. Tennemann’s direct and indirect influence is partially responsible for the popularity of the standard narratives of early modern philosophy based on the conflict between empiricism and rationalism.
That’s it for now. Come back next Monday for Gideon Manning‘s comments on the origins of the experimental-speculative distinction.
Reinhold on Empiricism, Rationalism, and the Philosophy without Nicknames
Alberto Vanzo writes…
There is a traditional way of narrating the development of early modern philosophy. I first studied it in high school and no doubt you are familiar with it. According to this narrative, the central dispute within early modern philosophy concerned epistemological matters:
- Do we have a priori knowledge of the world?
- Do we have innate concepts?
Rationalists answered that we do, whereas empiricists denied it. Eventually came Kant, who refuted empiricists and rationalists, sentenced the end of those movements, and embodied their insights within his own transcendental philosophy.
These days, this sort of narrative is regularly attacked for overstating the importance of epistemological matters and for being biased in favour of Kant’s philosophy. Who first framed that narrative? Some say it was Kant. Yet I argued in an earlier post that this is not the case. While Kant introduces the terms “empiricism” and “rationalism”, he does not view empiricism and rationalism as purely epistemological views. Moreover, he does not take his thought to be above empiricism and rationalism. He takes himself to be a rationalist.
Karl Leonhard Reinhold
Karl Leonhard Reinhold first spelled out the traditional historiographical framework in works from the early 1790s (such as On the Foundation of Philosophical Knowledge and the Contributions toward Correcting the Previous Misunderstandings of Philosophers, from which I will quote). In these years, Reinhold was articulating his own system, “Elementary Philosophy”. He distinguished it from Kant’s philosophy with these words:
- The Elementary Philosophy is therefore essentially different from the Critique of Pure Reason. And the philosophy of which it is a part […] can no more be called critical than it can empirical, rationalist or sceptical. It is philosophy without nicknames.
At this point, Reinhold makes some bold historiographical claims:
- The insufficiency of empiricism brought about rationalism, and the insufficiency of the latter sustained the other in turn. Humean scepticism unveiled the insufficiency of both of theses dogmatic systems, and thus occasioned Kantian criticism. The latter overturned one-sided dogmatism and dogmatic skepticism.
How did this all happen? First came Locke’s empiricism and Leibniz’s rationalism:
- The two philosophers laid down, one in the simple representations drawn from experience and the other in innate representations […], the only foundation of philosophical knowledge possible for the empiricists [on the one hand] and the rationalists [on the other.] And while their followers were busy disagreeing about the external details and the refinements of their systems, David Hume came along
and revealed their mistake. This was believing that we are able to know mind-independent things, either on the basis of simple mental representations drawn from experience (empiricism), or by means of innate concepts and principles (rationalism).
- Hume confronted this crucial issue about the conformity of impressions to their objects; this was what everybody had taken for granted without proof before his time, and he demonstrated that no proof can be offered that is without contradiction.
Hume’s mistake was assuming, like Locke and Leibniz, that the objects that impressions must conform to be true are mind-independent or, in Kant’s terms, things in themselves. Kant rejected that “groundless assumption by proving “that objective truth is entirely possible without knowledge of things in themselves”. Reinhold’s Kant takes objective truth to be the correspondence of our mental representations with mind-dependent, phenomenal objects. On the basis of this view, Kant answered the central question of what are the extension and limits of our cognitive powers. For Reinhold, answering this question enabled Kantians to solve the disputes in the fields of ethics and natural law, and even theology.
With his account, Reinhold places Kant above and beyond empiricism and rationalism. Reinhold takes epistemological issues on the foundation and limits of knowledge to be central to the whole philosophy of early modern age. In short, Reinhold has the epistemological and Kantian biases.
It is easy to see why Reinhold’s potted history of early modern philosophy was attractive for Reinhold’s contemporaries. From a historiographical point of view, it places four works that Reinhold’s contemporaries held in great esteem (Locke’s Essay, Leibniz’s New Essays, Hume’s Treatise, and Kant’s first Critique) within a single, coherent narrative. From a philosophical point of view, Reinhold places Kantian and post-Kantian philosophies that had become increasingly popular at the summit of the development of human reason.
Reinhold’s history of early modern philosophy is very sketchy. The first historian to flesh it out in great detail was Wilhelm Gottlieb Tennemann. Next time I will tell you about him.
