There are three principal means of acquiring knowledge... observation of nature, reflection, and experimentation. Observation collects facts; reflection combines them; experimentation verifies the result of that combination.

Knowledge is what we get when an observer, preferably a scientifically trained observer, provides us with a copy of reality that we can all recognize.
The true method of knowledge is experiment.
Observation is a passive science, experimentation an active science.
Knowledge is the life of the mind.
Knowledge is of two kinds. We know a subject ourselves, or we know where we can find information upon it.
Scientific inquiry starts with observation. The more one can see, the more one can investigate.
To learn means by practice, by inquiring, by analyzing to find out what is, not what was.
Knowledge is the eye of desire and can become the pilot of the soul.
To have real knowledge, one must understand the essence of things and not only their manifestations.
To acquire knowledge, one must study; but to acquire wisdom, one must observe.
