Hume, Kant & the Problem of Personal Identity

I never can catch myself at any time without perception, and never can observe anything but the perception." How does this statement by Hume problematize the philosophical notion of personal identity? How does Kant deal with this problem in his Critique of Pure Reason?

How to Approach

This question requires a detailed understanding of Hume’s skepticism regarding personal identity and how Kant attempts to overcome it. The answer should begin by explaining Hume’s bundle theory of self, emphasizing the role of perception. Then, it should articulate how this challenges traditional notions of a unified, enduring self. Finally, the answer must explain Kant’s transcendental idealism and the role of the ‘transcendental unity of apperception’ in constituting personal identity, contrasting it with Hume’s view. A clear comparison of both philosophers’ positions is crucial.

Introduction

The question of personal identity – what makes a person the same person over time – has been a central concern in philosophy. David Hume, a prominent empiricist, radically challenged the traditional metaphysical assumptions surrounding this concept. His assertion, “I never can catch myself at any time without perception, and never can observe anything but the perception,” encapsulates his skeptical stance. This statement denies the existence of a persistent self beyond a constantly changing stream of perceptions. This poses a significant problem for understanding how we can meaningfully speak of a continuous, unified self. Immanuel Kant, responding to Hume’s skepticism, offered a transcendental idealist account of the self, attempting to reconcile the subjective experience of identity with the possibility of objective knowledge.

Hume’s Problematization of Personal Identity

Hume’s skepticism stems from his empiricist methodology, which insists that all knowledge originates from sensory experience. He argues that when we introspect, we never encounter a stable, enduring ‘self’ but only a bundle of perceptions – sensations, thoughts, feelings – constantly in flux.

  • Bundle Theory of Self: Hume proposes that the self is not a substance or an entity but merely a collection or ‘bundle’ of these perceptions succeeding each other with inconceivable rapidity. There is no underlying ‘I’ that owns or unifies these perceptions.
  • Rejection of Substance: Hume rejects the notion of a ‘substance’ underlying these perceptions, arguing that we have no empirical evidence for such a thing. The idea of a self is simply a habitual association of perceptions.
  • Problem of Continuity: If the self is merely a bundle of perceptions, how can we account for the feeling of continuity and identity over time? Hume suggests this is due to resemblance and causation between successive perceptions, but this doesn’t establish a genuine, enduring self.

This view has profound implications. If there is no enduring self, concepts like moral responsibility and personal accountability become problematic. If ‘I’ am not the same ‘I’ who performed a past action, how can ‘I’ be held responsible for it?

Kant’s Transcendental Idealism and the ‘Transcendental Unity of Apperception’

Kant, deeply influenced by Hume, recognized the force of his skepticism but sought to overcome it. He argued that Hume’s mistake was to treat the self as an object of experience, something that could be empirically observed. Kant proposed a transcendental approach, focusing on the conditions that make experience possible.

  • Transcendental Idealism: Kant’s central claim is that our experience is not a direct reflection of reality ‘as it is in itself’ (the noumenal realm) but is shaped by the inherent structures of our minds (the phenomenal realm).
  • Transcendental Unity of Apperception: This is the key to Kant’s solution to the problem of personal identity. It is not an object of experience, but a necessary condition for having any experience at all. It is the ‘I think’ that must accompany all our representations.
  • The ‘I Think’ as a Principle: The ‘I think’ is not a perception itself, but a function of the understanding that synthesizes and unifies our perceptions into a coherent experience. It’s a principle, not an object.
  • Time as a Form of Intuition: Kant argues that time is a fundamental form of intuition, meaning it is a structure imposed by our minds on all experience. This explains why we perceive our experiences as occurring in a sequence, creating the illusion of a continuous self.

Comparing Hume and Kant

Feature Hume Kant
Nature of Self Bundle of perceptions Transcendental Unity of Apperception
Empirical Status Object of experience (but not found) Not an object of experience; a condition for it
Source of Identity Resemblance and causation between perceptions Synthesis of perceptions by the understanding
Metaphysical Status Skeptical; denies a substantial self Transcendental; posits a necessary, non-empirical self

Kant doesn’t claim to have *discovered* the self as an object, but rather to have identified the *condition* that makes the experience of a self possible. He shifts the focus from what the self *is* to how the self *functions* in constituting experience.

Conclusion

Hume’s radical skepticism regarding personal identity, stemming from his empiricist principles, effectively dismantled traditional metaphysical notions of a substantial self. He demonstrated that introspection reveals only a flux of perceptions, not a unified ‘I’. Kant, while acknowledging the validity of Hume’s critique, offered a compelling alternative through his transcendental idealism. By positing the ‘transcendental unity of apperception,’ he argued that the self is not an object of experience but a necessary condition for experience itself, thereby providing a framework for understanding the continuity and coherence of personal identity. Kant’s solution, though complex, represents a significant attempt to reconcile the subjective experience of selfhood with the demands of objective knowledge.

Empiricism
The philosophical doctrine that all knowledge is derived from sensory experience.

Kant’s philosophical view that our experience is shaped by the inherent structures of our minds, and that we can only know things as they appear to us (phenomena), not as they are in themselves (noumena).

Key Statistics

According to a 2023 Pew Research Center study, 68% of Americans believe in the existence of a soul, suggesting a widespread intuitive belief in a persistent self beyond physical existence.

Examples

Capgras Delusion

This psychiatric condition involves the delusion that a familiar person has been replaced by an imposter. It illustrates how our sense of personal identity relies not just on perceptual data, but on complex cognitive and emotional associations.

Frequently Asked Questions

Does Kant’s ‘transcendental unity of apperception’ mean he believes in a soul?

Not necessarily. Kant is careful to avoid making claims about things ‘in themselves’ (noumena). The transcendental unity of apperception is a necessary condition for experience, but it doesn’t prove the existence of a soul in the traditional metaphysical sense.
