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

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.

For many years I was engaged in journalism, writing articles and chronicles for the daily press without ever joining the staff of any newspaper.

There is something of the freshness of mind, of the lightness of spirit in Linne which for centuries has been linked in people's minds with the mountains of Sweden and Swedish joy in nature.

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

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.
