He is basically saying, we need to attatch numbers to some empirical observation so that we can analyse, reason about it, and form strategies to change it; if we cannot do the former, we cannot do the latter.
You appear to be saying if I cannot measure something, I cannot analyse or reason about it, but it’s possible to change it. What I can’t know is whether or not some change has occurred.
Basically phenomena occur in the empirical world, we analyse and reason about these phenomena in the theoretical world. The means by which we do this is measurement.
