Quantification, Practice, Speed of Light

When Bergson proposes that Experience is fundamentally Practical, he does not seem to consider the implication for his previous analysis of Quantifaction. For, the latter now becomes a tool in the modification of the environment.  Thus, the real value of Modern Physics is that its propositions are formulae for control and repetition, even if they pass through contemplative phases. Accordingly, as the Pragmatists insist, verifiability is a criterion of their Value.  Thus, for example, while that the Speed of Light is a constant is verifiable, and, indeed, has been verified, a verification procedure to test whether or not it is also the maximum Velocity seems lacking.  Hence, that proposition is meaningless, according to Pragmatism.
