The greatest disorder of the mind is to believe things because one wishes them to be so.

What is life? It is the continuous creation of new forms.

The scientific method is a process of successive approximations.

To doubt everything or to believe everything are two equally convenient solutions; both dispense with the necessity of reflection.

The greatest error of the mind is to believe things because one wishes them to be so.
