Abstract
Purpose: In the forthcoming book Partial Memories, Ernst von Glasersfeld presents a chronological patchwork of autobiographical memories. Constructivist Foundations selected six of the 92 sketches to provide a preview of this book. Content: The selected sketches cover the 1930s, when von Glasersfeld became interested in epistemology, and the 1970s, when he found experimental and argumentative support for his radical constructivism. Implications: The colorful life of von Glasersfeld gives an impression of how many turns it has taken him to construct his insights.
