The idea of the interaction of plant and human thus refers to the coexistence of humankind and the environment.
Circulating bodies of knowledge themselves become the characteristic of a society or an epoch.
The plant as a whole, as a living being with relations to other living beings, still appeared in phythotheological essays around 1800. In the middle of the 19th century, the plant is no longer discussed in this context. It is interieurized and becomes part of the bourgeois living culture and with time more and more a decorative object.
