ABSTRACT

Baker, Henry Beware of determining and declaring your Opinion suddenly on any Object; for Imagination often gets the Start of Judgement, and makes People believe they see Things, which better Observations will convince them could not possibly be seen: Therefore assert nothing till after repeated Experiments and Examinations in all Lights and in all Positions.

Bernard, Claude Observation, then, is what shows facts; experiment is what teaches about facts and gives experience in relation to anything.
