Among other works, the great early 20th century philosopher Edmund Husserl wrote his own Cartesian Meditations, an expanded version of lectures delivered in Paris in 1929. Husserl developed his own version of phenomenology, very different from Hegel’s, and his own version of transcendental subjectivity, very different from Kant’s. Throughout his career, he was concerned to criticize naive notions of objectivity. While disagreeing with a few of his fundamental principles, I enormously admire his nuanced development and intellectual honesty.
Husserl writes that “The aim of [Descartes’] Meditations is a complete reforming of philosophy into a science grounded on an absolute foundation” (Cartesian Meditations, p. 1). I think of philosophy as concerned with generalized, coherent interpretation of life and the world as an ongoing, never-finished project, rather than a completed rational “science”. But Husserl, with all his scruples about premature claims of objectivity, is famously provisional in most of his actual developments. As long as the ultimate “science” remains an aim and is not claimed as a present possession, we have not fallen into dogmatism. I think Husserl overall actually does better than Kant at avoiding overstated claims of “scientific” accomplishment.
According to Husserl, Descartes “gives rise to a philosophy turned toward the subject himself” (p. 2). I tend to worry more about illegitimate claims on behalf of a sovereign Subject than about premature claims to know about real objects, but both concerns are valid. “Philosophy — wisdom (sagesse) — is the philosopher’s quite personal affair. It must arise as his wisdom, as his self-acquired knowledge tending toward universality, a knowledge for which he can answer from the beginning, and at each step” (ibid).
The literal meaning of the Greek philosophia is “love of wisdom”. Some kind of wisdom, rather theoretical knowledge, was the main goal of ancient philosophy, from Plato and Aristotle through the Stoics, Epicureans, and Skeptics, all the way to the neoplatonists. An emphasis on wisdom as distinct from knowledge puts a “practical”, ultimately ethical dimension above all particular inquiries, whereas Latin scholastics focused on more technical debates about the truth of propositions, and early modern philosophy was permeated with ideals of pure science. I think it was really more the Kantian primacy of practical reason than the Cartesian cogito that initiated a partial turn back to the ethical concerns of the ancients. Some writers have suggested that claims for the revolutionary character of the cogito are more shaped by Kant’s interpretation and by the perception of Descartes as a precursor to Kant than by Descartes’ original.
Commentators have noted that ethical concerns are basically absent from Descartes’ Meditations. Kant and Husserl each in their own way reinfused broadly ethical concerns into Descartes’ preoccupations with the foundations of knowledge.
Husserl appeals to “the spirit that characterizes radicalness of philosophical self-responsibility” (p. 6). “Must not the demand for a philosophy aiming at the ultimate conceivable freedom from prejudice, shaping itself with actual autonomy according to ultimate evidences it has itself produced, and therefore absolutely self-responsible — must not this demand, instead of being excessive, be part of the fundamental sense of genuine philosophy?” (ibid).
This Husserlian appeal to autonomy, like Kant’s, ultimately still has to answer to the critiques of Hegel and Brandom (see In Itself, For Itself; Autonomy, Normativity; Self-Legislation?). Nonetheless, it is a high point in the development of the human spirit.
