No. The word you are looking for is "epistemology."
A method for determining truth is not itself a truth. Facts, or beliefs, are the result of this process.
Further, science is an empirical epistemology, as opposed to (e.g.) a rational one. So your appeal to logical principles is actually unfounded.
The above statements should not be construed to imply that rational epistemologies are "wrong." More to point out that the truths produced by each process are not equal. You may have a rational truth that "the sky is blue," and a thought experiment which proves this. You may also have an empirical truth that "the sky is blue", and empirical measurements that suggest that the light emitted is such-and-such a wavelength on average.
Both systems have problems. Rational systems can prove anything, depending on the axioms chosen. This can include things that are not empirically true: the sky is green, the Earth is flat, etc. Empirical systems cannot deliver exact results; nothing is ever entirely "true." Both systems cannot fully describe the universe -- in point of fact, nothing can, since that book would have to contain all information about every part of the universe.
The relative value of each system is mostly not measurable. Most systems make both rational and empirical claims. However, taking empiricism to extremes means not believing in anything but data. The opposite course involves believing anything that you can construct a rational explanation for. Philosophically, these things are equal. I don't presume to inform the reader which may be preferred.
