The distinction between facts and moral values is highly desirable: science and politics should keep to their own territories. Traditionally speaking, science can be seen as an ivory tower, which attempts to do its job in isolation of external influences. Politics does not mandate methods of scientific research or standards of justification; science is responsible for this by its own. Only by upholding this strict borderline can we aim for objective knowledge, which is independent of moral judgements. Likewise however, political considerations should not be mingled with or reduced to scientific ones, lest we degrade into scientism. Science and politics simply have different goals: whereas science is interested in questions about truth and falsity, politics is concerned with what is right or wrong. In this article, the authors discuss their opinions on the value of keeping politics and science separated.
