 A defender of constructive empiricism might suggest that unless we think of the activity of science in relation to some aim or other, we cannot properly understand that activity; and unless we understand as united under some general aim all the disparate many ways that science is undertaken, we cannot understand those many practices as parts of science (as opposed to, say, parts of religion or politics or …). The activity is rendered intelligible only in light of the point and purpose of undertaking it, and it is rendered intelligible as science only in light of a point or purpose shared with other activities regarded as scientific.
