Whenever one reads of the determination of the species, or opens a book on natural science and history, in whatever language, one inevitably comes across the name of Linne.

The grounding in natural sciences which I obtained in the course of my medical studies, including preliminary examinations in botany, zoology, physics, and chemistry, was to become decisive in determining the trend of my literary work.

During half a century of literary work, I have endeavoured to introduce the philosophy of evolution into the sphere of literature, and to inspire my readers to think in evolutionary terms.

A probing analysis of the problems of evolution forms the basis of my prose.

Money can't buy you happiness but it does bring you a more pleasant form of misery.

Before the palefaces came among us, we enjoyed the happiness of unbounded freedom and were acquainted with neither riches, wants, nor oppression.

When you write really good lyrics - and sometimes I did! - they are just a joy to sing.

Don't look for obscure formulas or mystery in my work. It is pure joy that I offer you. Look at my sculptures until you see them. Those closest to God have seen them.
