means The practice or ideal of judging things based on facts and evidence rather than personal feelings, biases, or perspective.

from From Latin 'objectum,' literally 'a thing thrown before' (the mind), built from 'ob-' (toward, against) and 'iacere' (to throw) — so an object is what's tossed in front of you to be looked at. 'Objectivity' as a philosophical term, contrasted with 'subjectivity,' was sharpened by the scholastics and later thinkers wrestling with the gap between the seen and the seer; the medieval Latin sense actually ran the opposite way from ours, but by the modern era it settled into meaning the world as it stands apart from any one viewer.
