Philosophia Botanica publishes Linnaeus’s teaching of botanical method
In 1751 Carl Linnaeus published Philosophia Botanica, the textbook form of his botanical method, including how to describe, name, and teach plants. In the causal graph this event strengthens Digital Learning Access, a driver that weakens Learning Poverty Rate (low- and middle-income countries) — an improving welfare path.
Read the full account
In 1751 Carl Linnaeus published Philosophia Botanica, the textbook form of his botanical method, including how to describe, name, and teach plants. It is a teaching object, not a statute of later codes. Artificial sexual classes are still the key; he admits a natural system is wanted.
Context
Uppsala lectures needed a portable text for students who would become clergy, physicians, and apostles. Printers shared the object. Sharing does not erase the lecturer. Buffon’s anti-system prose is the French foil.
Later competitions, monuments, translations, UNESCO listings, museums, and adaptations are not converted into extra lifetime acts.
Why it matters
Education path, modest-to-mid weight. High confidence on 1751.
Confidence is stated on the impact path, not hidden in adjectives. A method book is not Species Plantarum’s species list. Mixed effects of Philosophia Botanica publishes Linnaeus’s teaching of botanical method are separate paths.

What the sources establish
Linnean Society at https://www.linnean.org/learning/who-was-linnaeus (opens in a new tab) places Philosophia Botanica in the mid-career textbooks. Britannica at https://www.britannica.com/biography/Carolus-Linnaeus (opens in a new tab) independently dates the 1751 method book.

Established: Philosophia Botanica appeared in 1751. Not established: that it settled a natural system, which it did not. Contribution is recorded as He authored the textbook of method. Uppsala students heard it first as lectures. The impact note is A printed botanical method book widened access to classification practice beyond the Uppsala room. The dated heading stays Philosophia Botanica publishes Linnaeus’s teaching of botanical method on 1751-01-01, not a later statue, UNESCO listing, or school film. Later competitions, monuments, and adaptations are refused as extra lifetime acts of this person on this date. Bound 1 for linnaeus-philosophia-1751: the instrument remains Philosophia Botanica publishes Linnaeus’s teaching of botanical method (1751-01-01), with official locator https://www.linnean.org/learning/who-was-linnaeus (opens in a new tab) and independent locator https://www.britannica.com/biography/Carolus-Linnaeus (opens in a new tab), not a later museum door or a translated schoolbook treated as this act.
Shared responsibility is part of Philosophia Botanica publishes Linnaeus’s teaching of botanical method. Naming Carl Linnaeus does not delete co-authors, institutions, or later transmitters. The lag from 1751-01-01 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.
The contribution type is direct. That reading is an impact-path choice, not a property stored on the Fact itself.
If a number is not in the two records named above, it is not supplied here.
