ABSTRACT
Dynamically a science is the interplay of two factors: there are data revealed by experience, observation, experiment, measurement; and on the other hand, there is the constructive activity of mind. By themselves the data are objective, but they are also disparate, without significance, without correlation, without coherence. Of itself, the mind is coherence; spontaneously it constructs correlations and attributes significance; but it must have materials to construct and correlate; and if its work is not to be fanciful, its materials must be the data. Thus thought and experience are two complementary functions; thought constructs what experience reveals; and science is an exact equilibrium of the two.
