Die Krisis der europaïschen Wissenschaften und die transzendentale Phänemonologie (posthumously published in 1954; written in 1935-1936) is the last work Edmund Husserl ever wrote. Or rather: he wrote the first two parts of the book and was planning to write three more, but he passed away due to illness before being able to finish the book. This fact is in important, since his unfinished manuscript for the third part was collected and integrated with some personal notes, and then – together with the first two finished parts – published by Walter Biemel as one work.
This leads to the unavoidable problem of reading through a work that was still in progress and missing two fifths of its intended content. Add to this the fact that Husserl himself was a philosopher who radically developed his own ideas over a decades long career, and understanding the true intentions and meaning of Husserl’s final work becomes somewhat problematic. Then, why read it? Because Husserl went through a series of temporary philosophical phases over his career and hence picking up where he finished is the best way to understand both his ideas and the reasons why earlier ideas were replaced or modified. Also, it is (presumably) one of Husserl’s more readable works.
In order to understand the book, one has to understand Husserl’s career, which is not hard but it requires some familiarity with the historical tradition within modern philosophy (from Descartes onwards). Husserl, himself educated as both astronomer and mathematician, pretty soon switched to philosophy. This had to do with the radical breakthroughs in philosophy by the end of the nineteenth century: this was the time when both logic and mathematics were deepened by new philosophical discoveries. In Husserl’s time one of the more intriguing questions was the status of numbers, and this is where we have to start our trail.
In general, Husserl’s career can be divided into two phases. The first phase occupies itself with the development of phenomenology as descriptive psychology as a means to deal with the questions: What is a number? And, what is proposition? In short: Husserl delves into the status of the fundamental objects of mathematics and logic. The second phase occupies itself with the transformation of this descriptive psychology into a transcendental philosophy with accompanying method (transcendental phenomenology). Here, Husserl tries to analyse the status of the fundamental objects of the sciences (including both physics and psychology). In the end, Husserl stumbles onto a whole new method that allows him – or so he claims – to re-establish philosophy as a strict science, as the foundation of all of the other sciences (and the whole world – more on that later).
Now, first things first. At the end of the nineteenth century Bertrand Russell offered his own theory of numbers as an answer to the Platonism in mathematics (the notion of numbers as absolute existing ideas). Russell claimed numbers are nothing but sets of sets of concrete worldly objects – i.e. numbers are physical objects. Husserl (around 1891) disagreed and claimed numbers are properties of sets – i.e. sets are not physical objects (their elements are) but psychological activities. For Husserl, analysis of sets had to focus on the psychological act of ‘gathering together’ and reflection upon this collecting. In this, Husserl was influenced by his former inspiratory, Franz Brentano, a philosopher who founded the field of descriptive psychology as the foundation of scientific psychology (i.e. the description and classification of the fundamental objects that psychology then has to explain).
In short, for Husserl the foundation of mathematics consists in (1) clarifying the objects of the mathematical axioms – the task of the psychologist – and (2) deducing theorems from these axioms – the task of the mathematician.
An important contemporary logician, Gottlob Frege, rejected Husserl’s claim that numbers (as fundamental objects of mathematics) are psychological acts. According to Frege, if numbers are pure subjective psychological constructs; and if we have no access to other minds; then mathematics is not an objective but a subjective science (each mathematician constructs his own numbers). Frege’s solution: numbers objects existing apart from subjects, which are studied by the mathematician – i.e. numbers are platonic ideas that the mathematician contemplates
So here we have a curious circle. Russell couldn’t stand the notion of numbers as platonic ideas and claims numbers are logical constructs; Husserl claims this cannot be true since numbers don’t exist spatiotemporally and hence are psychological constructs; and Frege rejects this on the basis of the subjectivism of mathematics and returns to the concept of number as platonic idea. This interaction and unsatisfying conclusion illustrates the intellectual climate someone like Husserl started from.
Husserl, moving on from his analysis of numbers, proceeds to investigate the objects of logic, to try to get a deeper understanding of what’s going on. The central question: If logic is not an empirical science (i.e. based on experience), then what is the status of logical objects? The contemporary main perspective on this was John Stuart Mill’s conception of logical objects as psychological experience – logic occupies itself with self-experience of its own thinking acts, hence logic equals psychology.
In his Logical Investigations (1900/1901) Husserl destroys this view. According to him, Mill’s psychologism is faulty: logical laws are strict while psychological laws are statistical; logic does not operate on experimental data, psychology does; logical laws cannot be falsified empirically (someone just thinks fallacious – this doesn’t falsify the logical law), psychological laws can; and valid logical conclusions cannot be denied without a contradiction, while this isn’t the case in psychology. So logic isn’t psychology – what is going on here? Husserl concludes that logic is an a priori science and we should distinguish between the thinking act and the contents of the thought. When someone reasons, the content of his/her thoughts is a spatiotemporal, worldly realisation of some ideal species of this particular proposition. And to analyse a particular thinking act, especially the relationship between all the different instances of the act and its content, one has to – again – resort to descriptive psychology – also called phenomenology.
This might sound abstract, but it is fundamental to all of Husserl’s work. He basically claims that the meaning of a proposition is determined by (1) the subject (2) thinking (3) this particular content. The material in which this proposition is communicated is irrelevant – the phenomenologist should just study the subject, the thinking act and the content of the thought. So me claiming ‘it rains’ gets meaning from me thinking that it rains. This can only be analysed through reflecting on my own thought process. So on one hand we end up (again) with Platonism: logical propositions are worldly realizations of ideal propositions as such; and on the other hand we end up with a very traditional theory of language: words get meaning through our mental life.
Let’s take stock of all the above – the first phase in Husserl’s thinking. Through analysis of numbers and propositions Husserl finds a new method, descriptive psychology (reflection on psychological acts) and understand these objects as ideal objects (in the platonic sense).
The next phase in Husserl’s career was the development of this method of descriptive psychology, or phenomenology, and in so doing he stumbled onto a whole new philosophical question: the existence of the material world.
This problem is much easier to understand than all of the above. On the one side we have our everyday life of experiences (senses, motion, etc.) and on the other side we have the physical world as described by mathematics. Ever since the seventeenth century (starting with Descartes) the question arose how the physical world causes our experienced world. John Locke was the first to analyse our senses in order to understand how we process the sense-data and form concepts and conceptual relations. This started of the tradition of empirical psychology, which studies how the objective world causes impressions in our minds, which we experience.
For Husserl, the question becomes: What is the status of these experiences? To answer this question, he relies on René Descartes, who claimed that besides all the worldly material, the mind is another substance that exists. The mind receives all these incoming impressions and orders these according to a priori principles (like pre-existing categories). This theory of knowledge is something that Immanuel Kant would later offer as an answer to Hume’s scepticism that both experience and logic are subjective fictions. In the nineteenth century, this tradition culminated in theories like Helmholtz’s or Freud’s, who claimed that the world is nothing but a projection of our own a priori apparatus onto something that is unintelligible – i.e. the world is a construction of our own imagination.
Husserl claims ‘an unintelligible world, a world as such’ is meaningless. Since we have (by definition) no experience of it, there’s no reason to postulate its existence. No, we should analyse our personal experiences of the world, again using descriptive psychology (or phenomenology), and describe what happens when we think we experience things (without dealing with these things themselves or questions of truth). When we do so, we will realize that both the physicist and the psychologist – the one from a physical worldview; the other from a psychological worldview – presuppose an already existing, a given world. Husserl claims this proves that phenomenology shows that we first, a priori, constitute the given world of everyday experience, and we subsequently – when confronted by this world and reflecting on it – start to study it.
And now we have (finally) ended up with the core programme of Husserl’s later career. He transforms his phenomenology as descriptive psychology (as method to study experience) into a fundamental philosophical discipline. To understand why, one only has to connect the last two mentioned things: Husserl basically claims that human beings constitute the everyday world, the world that’s a priori given to us, and that all the objective sciences (including psychology) are founded on the presupposition of the existence of this world. So a philosophy that analyses and defines this a priori (or transcendental) world is a science that will lay the foundation for both our everyday psychological experiences and all other sciences.
What Husserl does is improve upon Kant’s transcendental idealism. He throws away Kant’s ‘world as such’ and puts our psychological life into its place. Next, we study the relationship between the psyche and the world, and we discover that the world is a representation based on mental experiences – i.e. psychology constitutes the physical world. A regularity in our psyche seems to constitute a stable, coherent and consistent world, a world in which experiences seem to make sense. We don’t encounter a world in which we touch a coffee mug but don’t see or smell it – all of our experiences seem to be stable over time and form a coherent and consistent unity.
But there’s a problem. All of our mental experiences – e.g. sensory experiences, kinaesthetic experiences, etc. – take place, through our own bodies, in the spatiotemporal world. But this world was constituted by our mental experiences to begin with. This is what Husserl calls the ‘paradox of human subjectivity’. Our experiences are dependent upon our psychological acts; our psychological acts are dependent on our bodily life; but our bodily life is dependent on our psychological acts. The solution to the problem lies, for Husserl, in recognizing that we have to distinguish between natural psychology (or consciousness) and transcendental psychology (or consciousness). We have a consciousness of our world – the domain of psychology – and we have a deeper, a priori, fundamental consciousness – the domain of transcendental philosophy.
And this, basically, is Husserl’s philosophical growth over a period spanning more than four decades. He started off by studying the fundamental objects of math (numbers) and logic (propositions); constructed a method to perform this feat (phenomenology, or descriptive psychology); and, through his study of the causal connection between the physical and our psychological worlds, transformed his method of descriptive psychology into a method (the transcendental reduction) that allows for a strict science of transcendental Being (transcendental phenomenology). To enter the transcendental state, one has to reduce the experiential world of one’s subjective psychology to the most abstract, general and most certain world. How? To throw all questions of certainty out of the window. Stop doubting your experiences and simply analyse how objects show themselves to you; perceive the perceiving; and try to discover, step by step, what it is that forms the foundation of this perceiving.
For Husserl, the study of the subject (me), the thinking act (perceiving) and the thought (the coffee mug) is the road to an understanding of the a priori state of consciousness. And this transcendental ego, ultimately, is what constitutes, through acts of intentionality, the world around us, and its derivative: the world of physics.
What has all this got to do with a book on the supposed crisis of the European sciences? A book written in the crisis of Nazi Germany, by a German Jew, who was forbidden to work as a professor and kicked out of the academy by one his former students, then rector, Martin Heidegger?
Well, the final step one has to take to answer this question, is to realize that the philosopher, according to Husserl, is the functionary of humanity. The philosopher is part of a historical process of understanding Being and in so doing, offer humanity a sense of meaning. This sounds overly pretentious – and, to me, it is – but one only has to realize that each of us, human beings, is – in essence – such a transcendental ego. And to reach this state, we all can use the transcendental reduction, reducing our psychological life to a transcendental ego, and in so doing we realize that all of our fellow human beings are both as much objects of our own making as well as transcendental subjects in themselves. This inter-subjectivity is an important part in Husserl’s plea and it allows us to understand his broader claim.
Now where does the philosopher, as functionary of humanity, fit in? The fundamental task of the philosopher is to converse with past philosophers, and to take philosophy to the next step. Husserl, in a Hegelian fashion, claims modern philosophy was invented by Descartes and was led astray by the objectivist/empiricist psychologists, and that he, Husserl, with his discovery of transcendental phenomenology has ended all the historical drama. He has discovered humanity’s destiny, or ‘telos’ (goal) – and this is nothing but realizing pure reason. Reason will form the foundation of both our everyday (psychological) world as well as the objective world of the sciences. Or at least in theory, since Husserl claims he is very pessimistic and he sees irrationality all around him. Anno 1936 this has to be seen in light of the Nazi’s, but more so in light of the underlying philosophical currents: Nietzsche’s existentialism (claiming any foundation of anything was impossible – the best you can do is act on your Will to Power) was particularly dominant, but one gets the feeling that Husserl primarily fulminates against the metaphysical pretensions of a Heidegger, who threw any scientific aspirations out the window and solely focused on the given world, the world of everyday, as basis for human existence. (And Husserl saw what that led to…)
So on the one hand, the philosopher forms a community with past philosophers and tries define Being in its transcendental pureness and in so doing offer humanity a meaning (‘Sinn’); and on the other hand, this whole road to salvation seems almost totally cut off from the current road of destruction and mayhem that European humanity is taking.
I used the word ‘salvation’ on purpose, since this leads me to the final remark of this review. Husserl sees the transcendental ego, as foundation of reality, as immortal. Almost by definition, since space and time only exist in the constituted, objective world – of which the pure subject is the main spring. It basically reproduces the old Kantian problems: since the subject is unbounded by both space and time, it is deemed to be infinite. From this it follows that we have an infinite consciousness as fountainhead for the finite world. Without putting words into Husserl’s mouth, I feel suspicious about this whole idea for two reasons:
1. An infinite consciousness, independently existing from the material world, doesn’t only sounds like Cartesian dualism (which is philosophically problematic: How does the immaterial mind interact with the material world?), but it also smells like the Christian concept of an immortal soul – some entity that is imperishable that remains after the material world is destroyed. Husserl’s whole attempt seems to me a neat way to re-introduce Christian metaphysics in the form of a rational theology.
2. Why a rational theology? Well, because Husserl’s whole metaphysical system leads to idealism à la Berkeley. According to Berkeley, an eighteenth century philosopher, all that is, is experienced. Yet, I do not experience everything (for example my laptop when I’m not looking). It exists as an idea, yet I can’t prove that it exists objectively. But luckily we have an infinite God, who is good and all-knowing, and hence guarantees us a stable, coherent and consistent world – a world in which my laptop remains objectively there even when I’m not experiencing it. To me such philosophy is rather absurd (although interesting), but with Husserl this absurdism is combined with theological notions.
First, he proclaims himself to be a functionary of mankind, someone who – through contemplation from behind his desk – will offer mankind a better, more nobler goal than the current road she’s taking. If this doesn’t sound messianic, then what does? Second, even if the whole system stands, the one thing that Husserl leaves unexplained is who or what causes this regularity in our psyche? The mechanism that constitutes the everyday world in such a fashion that we experience it in a stable, consistent and coherent way? I can imagine a world in which my experiences of the apparent world are inconsistent – for example I see my laptop but cannot feel it, or vice versa. So there has to be a reason the world is thus and not otherwise.
Husserl, being a converted Protestant, seems to have been unable – although he tries his best to work out a very interesting, metaphysically neutral edifice on which to build all of reality – to shake off his Christian feathers. But this is simply me, a layman, guessing and interpreting, so take it for what it’s worth.
