Knowledge - Wikipedia
https://en.wikipedia.org/wiki/Knowledge
Knowledge is a familiarity or awareness, of someone or something, such as facts (descriptive knowledge), skills (procedural knowledge), or objects (acquaintance knowledge), often contributing to understanding. By most accounts, knowledge can be produced in many different ways and from many sources, including but not limited to perception, reason, memory, testimony, scientific inquiry, education, and practice. The philosophical study of knowledge is called epistemology.
