  Ignorance, Science, Doubt

• Men who have excessive faith in their theories or ideas are not only ill prepared for making discoveries; they also make very poor observations. Of necessity, they observe with a preconceived idea, and when they devise an experiment, they can see, in its results,only a confirmation of their theory. In this way they distort observation and often neglect very important facts because they do not further their aim.

  Claude Bernard

  Science, Men, Discovery

• When entering on new ground we must not be afraid to express even risky ideas so as to stimulate research in all directions. As Priestley put it, we must not remain inactive through false modesty based on fear of being mistaken.

• 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.

• Put off your imagination, as you put off your overcoat, when you enter the laboratory. Put it on again, as you put on your overcoat, when you leave.

  Claude Bernard

  Science, Imagination, Laboratory

• [Those] who have an excessive faith in their theories or in their ideas are not only poorly disposed to make discoveries, but they also make very poor observations.

  Claude Bernard

  Science, Discovery, Ideas

• The joy of discovery is certainly the liveliest that the mind of man can ever feel.

  Claude Bernard

  Science, Men, Discovery

  Claude Bernard (2012). “An Introduction to the Study of Experimental Medicine”, p.239, Courier Corporation

• Effects vary with the conditions which bring them to pass, but laws do not vary. Physiological and pathological states are ruled by the same forces; they differ only because of the special conditions under which the vital laws manifest themselves.

  Claude Bernard

  Science, Law, Special

  Claude Bernard “Experimental Medicine”, Transaction Publishers

• Real science exists, then, only from the moment when a phenomenon is accurately defined as to its nature and rigorously determined in relation to its material conditions, that is, when its law is known. Before that, we have only groping and empiricism.

  Claude Bernard

  Real, Science, Law

  Claude Bernard “Experimental Medicine”, Transaction Publishers

• 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. This sort of control, by means of reasoning and facts, is what constitutes experiment, properly speaking; and it is the only process that we have for teaching ourselves about the nature of things outside us.

  Claude Bernard

  Teaching, Mean, Science

• Obervation is a passive science, experimentation is an active science.

  Claude Bernard

  Science, Observation, Passive

• We must never make experiments to confirm our ideas, but simply to control them.

  Claude Bernard

  Science, Ideas, Experiments

  Claude Bernard “Experimental Medicine”, Transaction Publishers

• It is impossible to devise an experiment without a preconceived idea; devising an experiment, we said, is putting a question; we never conceive a question without an idea which invites an answer. I consider it, therefore, an absolute principle that experiments must always be devised in view of a preconceived idea, no matter if the idea be not very clear nor very well defined.

  Claude Bernard

  Science, Views, Ideas

  Claude Bernard (2012). “An Introduction to the Study of Experimental Medicine”, p.52, Courier Corporation

• In the philosophic sense, observation shows and experiment teaches.

  Claude Bernard

  Science, Observation, Teach

  Claude Bernard (2012). “An Introduction to the Study of Experimental Medicine”, p.35, Courier Corporation

• With the aid of these active experimental sciences man becomes an inventor of phenomena, a real foreman of creation; and under this head we cannot set limits to the power that he may gain over nature through future progress of the experimental sciences.

  Claude Bernard

  Real, Science, Men

  Claude Bernard “Experimental Medicine”, Transaction Publishers

• In the patient who succumbed, the cause of death was evidently something which was not found in the patient who recovered; this something we must determine, and then we can act on the phenomena or recognize and foresee them accurately. But not by statistics shall we succeed in this; never have statistics taught anything, and never can they teach anything about the nature of the phenomenon.

  Claude Bernard

  Science, Statistics, Succeed

  Claude Bernard (2012). “An Introduction to the Study of Experimental Medicine”, p.160, Courier Corporation

• Ardent desire for knowledge, in fact, is the one motive attracting and supporting investigators in their efforts; and just this knowledge, really grasped and yet always flying before them, becomes at once their sole torment and their sole happiness. Those who do not know the torment of the unknown cannot have the joy of discovery which is certainly the liveliest that the mind of man can ever feel.

  Claude Bernard

  Knowledge, Science, Men

  Claude Bernard (2012). “An Introduction to the Study of Experimental Medicine”, p.239, Courier Corporation

• Proof that a given condition always precedes or accompanies a phenomenon does not warrant concluding with certainty that a given condition is the immediate cause of that phenomenon. It must still be established that when this condition is removed, the phenomen will no longer appear.

  Claude Bernard

  Science, Doe, Causes

  Claude Bernard, Henry Copley Greene (1957). “An Introduction to the Study of Experimental Medicine”, p.55, Courier Corporation
