Review by Michael Beach
This work by David Bloor repasses the strong program of sociology and the creation of knowledge. He was a proponent of a framework called the sociology of scientific knowledge (SSK). The strong program suggests that technological advancements are primarily a function of social factors. The alternative, the weak program, doesn’t go so far, but looks at failed technologies and asserts social factors leading to their demise. After making a number of SSK arguments, Bloor looks at mathematics as an example. From the wisdom of the crowds example of ox-weight estimation, to the arguments against crow-sourcing for understanding the world, Bloor shares chapters on ‘naturalistic’ math followed by asking if there can be ‘alternative’ math.
For Bloor, and other proponents of SSK, naturalistic views are partial and don’t go far enough. Over time, other philosophers of science have pointed to Bloor’s own argument vulnerabilities in more or less ignoring technological and scientific effects on society. He admits there is some influence, but describes the influence seemingly like a form of feedback, but not so much as a changing factor. SSK leans away from technological determinism as have many other philosophical frameworks. Perhaps David Bloor and the school of SSK takes that leaning away too far. One argument he makes relates to symmetry. In this specific definition, all ideas should be approach as having equal weight until proven different. He argues “Our everyday attitudes are practical and evaluative, and evaluations are by their nature asymmetrical” (Bloor 1991, 175). Bloor shares examples of other philosophers inducing other forms of symmetry. Bloor’s position of practicality and ‘common sense’ is part of his justification of asymmetry between social influence on technology as opposed to technological influence on society.
