This abstract examines the relationship between philosophy and "common sense," challenging the idea that common sense serves as a reliable foundation for philosophical inquiry. The author contends that what is perceived as self-evident is actually the byproduct of past philosophies that have permeated public consciousness over time. These concepts, once original mental constructs, became so ingrained that their philosophical origins were forgotten, leading them to be accepted as universal truths. The text argues that every "obvious" truth was first a distinct thought that had to be conceptualized and integrated into general awareness. Consequently, philosophy should not rely on common sense but should instead investigate it as a collection of historical residues. By recognizing common sense as a result of previous intellectual movements, philosophers can avoid mistaking cultural prejudices for fundamental reality. This highlights the need for a reflexive approach to understanding how human knowledge is historically conditioned and shaped by the evolution of thought throughout history.
