This philosophical fragment explores the dialectical relationship between the thought and the unthought, as well as the spoken and the unspoken. It posits that just as every spoken word carries with it a horizon of the unspoken, every thought is inherently accompanied by a dimension of the unthought. This concept suggests that human cognition and communication are never exhaustive or self-contained; rather, they exist within a broader context of potentiality and hidden meanings. The unthought is not merely a void or a failure of logic, but a constitutive element that provides the necessary background and depth for explicit thinking. By drawing this parallel, the text invites a deeper reflection on the limits of language and the nature of philosophical inquiry. Dated to 1994, this short yet profound reflection emphasizes that the unspoken and the unthought are not external to expression and reason, but are vital, ever-present components that shape the boundaries and possibilities of human understanding.
