“Man does not limit himself to seeing; he thinks and insists on learning the meaning of phenomena whose existence has been revealed to him by observation. So he reasons, compares facts, puts questions to them, and by the answers which he extracts, tests one by another.

“In a word, I consider hospitals only as the entrance to scientific medicine; they are the first field of observation which a physician enters; but the true sanctuary of medical science is a laboratory; only there can he seek explanations of life in the normal and pathological states by means of experimental analysis.” LifeFirstsMeanStatesScienceFieldsNormalMedicineMedicalObservationAnalysisExplanationHospitalsPhysiciansLaboratorySanctuaryEntrancesMedical Science Book:An Introduction to the Study of Experimental Medicine Source: An Introduction to the Study of Experimental Medicine
“It has often been said that, to make discoveries, one must be ignorant. This opinion, mistaken in itself, nevertheless conceals a truth. It means that it is better to know nothing than to keep in mind fixed ideas based on theories whose confirmation we constantly seek, neglecting meanwhile everything that fails to agree with them.” KnowsMindMeanSaidIdeasScienceOpinionKnowledgeFailingTheoryDiscoveryAgreeIgnorantFixedAgreementNeglectNeverthelessMistakenConfirmation Author:Claude Bernard
