Peter Engelmann's book explains deconstruction as a philosophy, highlighting its connections within philosophy and its anti-totalitarian political motivation, which is essential for understanding it. Deconstruction, the philosophical approach of Jacques Derrida, is the most successful yet least known philosophical innovation since Heidegger's fundamental ontology. In countless branches, deconstruction has established itself in various artistic and literary practices, without a clear understanding of this term and philosophical strategy. The anti-totalitarian political motivation of deconstruction, which is crucial for its understanding, has been almost completely overlooked. In fact, deconstruction makes it difficult to describe in sober scientific language because it systematically questions every last conceptual determination.
