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

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

Excess Faith Ideas Observation Poor Theory
Theories are like a stairway; by climbing, science widens its horizon more and more, because theories embody and necessarily include proportionately more facts as they advance.

Science increases our power in proportion as it lowers our pride.

Our ideas are only intellectual instruments which we use to break into phenomena; we must change them when they have served their purpose, as we change a blunt lancet that we have used long enough.
CLAUDE BERNARD

Break Change Enough Ideas Instrument Intellectual Purpose
The science of life is a superb and dazzlingly lighted hall which may be reached only by passing through a long and ghastly kitchen.
CLAUDE BERNARD
