The document discusses engineering realism from a micro-meso-macro perspective. It argues that engineering reality consists of both material and social realities, and that engineering projects are carried out by engineering communities rather than individuals. It proposes analyzing engineering using a micro-meso-macro framework, where the micro level refers to individuals, the meso level refers to engineering communities, and the macro level refers to societies and humanity. Adopting this framework would provide a new way to study philosophical issues in engineering.
