The ontology of engineering is concerned with understanding the fundamental nature of engineering knowledge, artifacts, and practices, rather than specific engineering applications or technologies.

Herbert Simon is considered a pioneer in the field of engineering ontology for his work on the nature of engineering knowledge and design, particularly his book 'The Sciences of the Artificial'.

Engineering anthropology is a field that examines the relationship between engineering artifacts and the social and cultural context in which they are created and used, exploring the impact of technology on society and vice versa.

Embodied knowledge is a concept in engineering ontology that emphasizes the idea that engineering artifacts are not just physical objects but also embody the knowledge and intentions of their creators, reflecting the engineering design process and the intended purpose of the artifact.

Value-laden design is a concept in engineering ontology that recognizes that engineering artifacts are not neutral objects but can embody social and political values and assumptions, reflecting the values and priorities of the designers and the society in which they are created.

Lewis Mumford, an American historian and philosopher, argued that engineering artifacts are not merely tools but can also be seen as expressions of human creativity and artistry, reflecting the cultural and aesthetic values of the society in which they are created.

Unintended consequences is a concept in engineering ontology that recognizes that engineering artifacts can have unintended and often unforeseen effects on the social and natural world, highlighting the complex and unpredictable nature of technological development.

Social constructivism is a concept in engineering ontology that emphasizes the importance of understanding the social and cultural context in which engineering artifacts are created and used, recognizing that technology is shaped by social and cultural factors and, in turn, shapes society and culture.

Technological evolution is a concept in engineering ontology that recognizes that engineering artifacts can undergo changes and transformations over time, evolving in response to changing needs, technologies, and social contexts.

Michel Foucault, a French philosopher, argued that engineering artifacts are not merely physical objects but also embody social and political power relations, reflecting the power structures and ideologies of the society in which they are created.

Technological mediation is a concept in engineering ontology that recognizes that engineering artifacts can mediate the relationship between humans and the natural world, shaping the way humans interact with their environment and influencing their perception and understanding of the natural world.

Albert Borgmann, an American philosopher, argued that engineering artifacts are not merely tools but can also be seen as expressions of human values and aspirations, reflecting the hopes, fears, and desires of the society in which they are created.

Technological embodiment is a concept in engineering ontology that recognizes that engineering artifacts can have a profound impact on human identity and agency, shaping the way humans perceive themselves and their relationship with the world, as they become embedded in human practices and routines.

Hannah Arendt, a German-American philosopher, argued that engineering artifacts are not merely physical objects but can also be seen as expressions of human freedom and creativity, reflecting the human capacity to transform the world and create new possibilities.

Technological hermeneutics is a concept in engineering ontology that recognizes that engineering artifacts can have a profound impact on the way humans experience and understand the world, shaping their perception of reality and their relationship with nature, as they mediate the human experience of the world.
