Structured Representations — Thoughts Without Content Are Empty

What does it mean to think? And when a thought is "about" something — a face, a fear, a future plan — what exactly is happening inside the mind?

This seminar paper, written for the Seminar Neuronale Netze — Symbolverarbeitung — Kognition, digs into one of philosophy's most stubborn puzzles: the nature of mental representation. It moves from classic debates in the philosophy of mind — Searle's Chinese Room, Dreyfus's critique of AI, the problem of intentionality — through information theory and semiotics, and into contemporary cognitive science.

Along the way, it engages Frances Egan's provocative Deflationary Account of Mental Representations: the idea that mental content is not some deep metaphysical fact about the mind, but a useful interpretive gloss we apply for explanatory purposes. And it examines Gary Marcus's structural demands on any adequate theory of mind — recursion, systematicity, the distinction between individuals and kinds — and asks whether neural networks can ever truly meet them.

Thoughts without content are empty, intuitions without concepts are blind. — Kant, Critique of Pure Reason, 1787
