# Later Systema editions keep and thicken medicalised human ranks

Date: 1766

## The fact

In 1766–68 [Carl Linnaeus](/people/carl-linnaeus)’s twelfth edition of Systema Naturae continued the ranked human varieties of 1758, still mixing skin, humoral temperament, and alleged character inside a medical professor’s book. A physician who teaches materia medica also teaches which peoples are phlegmatic or inventive.

## Context

He could have dropped moral lines. He did not. Uppsala teaching gave the table classroom force. Printers shared the later edition. Sharing does not erase the author. Later biological racism is reception that found a convenient textbook; the textbook is still his.

If a number is not in the two records named above, it is not supplied here.

## Evidence and sources

Linnean Society at https://www.linnean.org/learning/who-was-linnaeus/linnaeus-and-race notes that later editions carried and adjusted the ranked varieties. Uppsala University at https://www.uu.se/en/news/2021/2021-05-07-linnaeus-complicated-relationship-with-racism independently treats hierarchy as his, with the African always last across editions.

## Significance

Health-knowledge harm path of modest-to-mid weight. High confidence the later edition still ranked varieties. 1758 remains the first expanded table; 1766 is continuance.

Later competitions, monuments, translations, UNESCO listings, museums, and adaptations are not converted into extra lifetime acts.

## What is established and what is not

Established: post-1758 Systema editions in his lifetime still ranked human varieties with medicalised traits. Not established: a unique clinic that dosed patients by those lines in 1766. Contribution is recorded as He continued to issue Systema editions after 1758 with human varieties still ranked. Printers produced the twelfth edition of 1766–68. The impact note is Repeating humoral medical stereotypes of human varieties in a physician’s catalogue is a health-knowledge harm path, his later edition not only later misuse. The dated heading stays Later Systema editions keep and thicken medicalised human ranks on 1766-01-01, not a later statue, UNESCO listing, or school film. Printers, unnamed clerks, and later editors may appear in the same file without becoming this instrument. Later competitions, monuments, and adaptations are refused as extra lifetime acts of this person on this date.

The contribution type is direct. The attached driver is health-system-capacity. The welfare reading used in this dossier is worsening. That reading is an impact-path choice, not a property stored on the Fact itself.

Confidence is stated on the impact path, not hidden in adjectives. 1766 continuance is not a later Blumenbach treatise. Mixed effects of Later Systema editions keep and thicken medicalised human ranks are separate paths.

Shared responsibility is part of Later Systema editions keep and thicken medicalised human ranks. Naming Carl Linnaeus does not delete co-authors, institutions, or later transmitters. The lag from 1766-01-01 to any measured indicator is not treated as zero. Alternative explanations — weather, other armies, later statutes, or independent cultural change — remain live where the sources do not close them.
