w. h. hudson had an early contact with the origin of species. he may have read it in the same year of its publication (1859). this reading brought him close to a naturalist philosophy that, in turn, took him away from an education in religious practice, fostered by his mother, and made him adopt a critical evolutionist position. in fact, he contradicted darwin's observations, which he latter reviewed, in addition to mentioning him in the second edition of the origin of species (1888). also, there are numerous quotations of darwin in hudson's works. even though differences can be noted, certain general topics on evolutionism may be easily recognized throughout his production. this paper attempts to move forward in these aspects in order to identify how deeply the evolutionist perspective influenced hudson's conception of the world.
