The true method of knowledge is experiment.
Sentiment: POSITIVE
Knowledge is the life of the mind.
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.
Everything is an experiment.
When the scientific method came into being, it gave us a new window on the truth; namely, a method by laboratory-controlled experiments to winnow true hypotheses from false ones.
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.
If you do an experiment and it gives you what you did not expect, it is a discovery.
Knowledge is true opinion.
Knowledge is power.
It is an acknowledged truth in philosophy that a just theory will always be confirmed by experiment.
Knowledge is knowing that we cannot know.
