The principle of prudence is not respect for science, but a pragmatic attitude towards the application of science. The achievement of scientific research achievements and their social recognition often represent huge empirical interests or even the lifelong achievements of scientists, so it is difficult to ensure that scientists will not relax the requirements of scientific principles and break the rules; the socialization of scientific research achievements is often linked to the interests of enterprises, enterprises will inevitably deliberately conceal the harm when pursuing profits. Because of the unknown factors and dangers of scientific research, the difficulty and time span of discovery are too large, even if scientists and enterprises adhere to moral principles, it is difficult to guarantee that the potential harm of scientific research achievements can be found.
The intended emphasis in this passage is that we should adopt a cautious attitude towards the application of scientific achievements.
