Men are not allowed to think freely about chemistry and biology: why should they be allowed to think freely about political philosophy?
Each department of knowledge passes through three stages. The theoretic stage; the theological stage and the metaphysical or abstract stage.
Every attempt to employ mathematical methods in the study of chemical questions must be considered profoundly irrational and contrary to the spirit of chemistry... If mathematical analysis should ever had prominent place in chemistry - an aberration, which is happily almost impossible - it would be a rapid and widespread degeneration of that science.
