that studies the "practice of designing and creating artifacts", and the "nature of the things so created." It emerged as a discipline over the past two centuries, and has grown "considerably" since the 1970s. The ''humanities philosophy of technology'' is concerned with the "meaning of technology for, and its impact on, society and culture". Initially, technology was seen as an extension of the human organism that replicated or amplified bodily and mental faculties. Marx framed it as a tool used by capitalists to oppress the proletariat, but believe technology would be a fundamentally liberating force once it was "freed from societal deformations". Second-wave philosophers like Ortega later shifted their focus from economics and politics to "daily life and living in a techno-material culture," arguing that technology could oppress "even the members of the bourgeoisie who were its ostensible masters and possessors."

Relation to science and engineering

Engineering is the process by which technology is developed. It often requires problem-solving under strict constraints. Technological development is "action-oriented", while scientific knowledge is fundamentally explanatory. Polish philosopher
Henryk Skolimowski Henryk Skolimowski (4 May 1930 in Warsaw – 6 April 2018 in Warsaw) was a Polish people, Polish philosopher. He completed technical studies, musicology and philosophy in Warsaw. He received his Ph.D. in philosophy from Oxford University. The st ...

between scientific discovery and technological innovation has been debated by scientists, philosophers and policymakers. Because innovation is often undertaken at the edge of scientific knowledge, most technologies are not derived from scientific knowledge, but instead from engineering, tinkering and chance. For example, in the 1940s and 1950s, when knowledge of turbulent combustion or fluid dynamics was still crude, jet engines were invented through "running the device to destruction, analyzing what broke ..and repeating the process". Scientific explanations often follow technological developments rather than preceding them. Many discoveries also arose from pure chance, like the discovery of
penicillin Penicillins (P, PCN or PEN) are a group of β-lactam antibiotics originally obtained from ''Penicillium'' moulds, principally '' P. chrysogenum'' and '' P. rubens''. Most penicillins in clinical use are synthesised by P. chrysogenum using ...

through frequent trial and error are more likely to lead to useful innovations than research that aims to reach specific outcomes. Despite this, modern technology is increasingly reliant on deep, domain-specific scientific knowledge. In 1979, an average of one in three patents granted in the U.S. cited the scientific literature; by 1989, this increased to an average of one citation per patent. The average was skewed upwards by patents related to the pharmaceutical industry, chemistry, and electronics. A 2021 analysis shows that patents that are based on scientific discoveries are on average 26% more valuable than equivalent non-science-based patents.
