Greetings
When I say measurement from a quantitative perspective, I mean finite measurements (something bounded by space and time).

For example, when one says that it is 32 degrees Fahrenheit? Some may say that that is cold. While others may say that it is warm.

It is a matter of perspective.

But 32 degrees is measureable by an instrument while saying that it is cold or warm is measured by the skin which senses is relative to the person feeling the cold/hot.

When relating to the physical/finite world, mathematics can be used to show how the physical world must be in equilibrium.

But when dealing with the meta-physical, our Iceptions of the mind comes into play in our definition of things that do not exist in space or time (thoughts, ideas, events).

".. the progress of science has itself shown that there can be no pictorial representation of the workings of nature of a kind that would be intelligible to our limited minds. The study of physics has driven us to the positivist conception of physics. We can never understand what events are, but must limit ourselves to describing the pattern of events in mathematical terms: no other aim is possible .... the final harvest will always be a sheaf of mathematical formulae. These will never describe nature itself, but only our observations on nature." (Sir James Jeans, 1942)
