What it means
The number of species alive today equals exactly what was originally created at the beginning of time. Each original form reproduced only its own kind, passing down its structure faithfully through generations. What we observe in nature now — every distinct body plan and form — represents one of those original created types, unchanged in fundamental structure from its first appearance.
Relevance to Carl Linnaeus
This quote is foundational to Linnaeus's life work. As the architect of binomial nomenclature and the Systema Naturae, he needed a stable, fixed concept of species to build taxonomy upon. His entire classification system depended on species being discrete, countable, and permanent — chaotic species boundaries would undermine the ordered natural hierarchy he devoted his career to documenting.
The era
In 18th-century Europe, natural theology dominated science: God's creation was orderly and fixed. Linnaeus worked before Darwin, when fixity of species was orthodox. The Scientific Revolution had made cataloguing nature prestigious, and explorers were returning with thousands of unknown specimens. Determining what counted as a distinct species versus a variety was an urgent practical and theological question for naturalists of his era.
