All the vital mechanisms, varied as they are, have only one object, that of preserving constant the conditions of life in the internal environment.

Claude Bernard

The constancy of the internal environment is the condition for free and independent life: the mechanism that makes it possible is that which assured the maintenance, with the internal environment, of all the conditions necessary for the life of the elements.

Claude Bernard

Constant, or free, life is the third form of life; it belongs to the most highly organized animals. In it, life is not suspended in any circumstance, it unrolls along a constant course, apparently indifferent to the variations in the cosmic environment, or to the changes in the material conditions that surround the animal.

Claude Bernard

The stability of the internal medium is a primary condition for the freedom and independence of certain living bodies in relation to the environment surrounding them.
