In
his Reveries of a Solitary Walker, Rousseau was depressed nearly all of
the time until he was rescued by botany. The study of plant diversity in nature
saved him from complete depression. It works for me, and I highly recommend it.
Botany is, among many other things, the pursuit that saved Rousseau from
insanity.
Rousseau
did not just glance at flowers and grass and say, yeah, they are pretty. He
looked closely at them. He observed them and thought about them. Above all, he
wanted to know what they were. In Walk 2, he describes his joy at seeing Picris
hieracioides the hawkweed; Bupleurum falcatum, the hare’s ear; and Cerastium
aquaticum, the mouse-eared chickweed. These are all very common weeds, but
Rousseau noticed their beauty. Alas, in Walk 2, he slipped back into
depression, and these flowers just reminded him of how much of his life he had
wasted by not being a botanist. I think.
Rousseau
spent the two happiest months of his life on St. Peter’s Island in Lake Bienne
in Switzerland. He thought that, on that isolated island, he was free from the
condemnation of the government authorities in Berne. In Walk 5, he describes
his “botanical fervor.” He was particularly enchanted by the alder-buckthorn (Frangula
alnus), the willow-weed (Epilobium ciliatum), and wild thyme. He
also mentioned the toothwort (Dentaria), wild cyclamen, the bird’s-nest
orchid Neottia nidus-avis (which has no chlorophyll), Laserpitium
gallicum, and the lycopodium clubmoss. He ate the very tart berries of the
sea buckthorn tree (Hippophae rhamnoides). I tried them, and didn’t like
them, but they are raised commercially for cosmetics. He was as happy as a
child playing with the exploding capsules of the Himalayan balsam (Impatiens
glandulifera). I can attest to the surprising joy of having these capsules
explode in my hand, and my grandkids liked it even more. Rousseau briefly
returned to childhood happiness. This was his one happiness, aside from sex.
I
got lucky. My job (as a university botany professor) required me to spend a lot
of time looking at and for plants in natural habitats, and leading students on
field trips.
But
Rousseau’s stresses could not be completely forgotten, even in paradise on St.
Peter’s Island. Actually there were two islands, and Rousseau imagined that,
because the big and the powerful always consume and destroy the small and weak
in this world, the big island would someday consume the small one. My own
experience coincides with Rousseau’s. When I was sitting on a rock in the
middle of a rushing stream in Wyoming, in the middle of teaching a field botany
course to some of the best students I have ever had, I could not ignore the
pain I felt from the office politics back at the university where I worked,
where our department chair enjoyed making people feel bad about themselves
(according to other people who knew him).
Rousseau
would use his botanical ecstasies to launch into thinking about other topics.
Walk 6 begins with a wildflower hike near Fontainebleu. He was enjoying doing
this good thing—but did it really count as personal goodness if he enjoyed
doing good things? He wanted his enemies to suffer—but he could think of no
greater suffering to visit upon them than for them to know he was happy in
spite of them.
He
wished he could know all the plants on Earth. They are, he said, the clothing
of the Earth. They are the only spectacles of Nature of which we cannot grow
weary. He much preferred the Greek philosopher-botanist Theophrastus, who loved
plants for their own sake, over Dioscorides, for whom plants were only valuable
because of the medicines they contained.
I find this 1888 line drawing fascinating.
Notice the botanist, despite his serious demeanor and despite the shabbiness of
his house, is happy explaining a thistle (?) to two fellow seekers of wisdom.
One of them is a winsome young woman. The wonders of botany can, in fact,
attract a mate—worked for me. But notice also that Karl Marx is listening to
him! I didn’t think Karl Marx listened to anyone! Oh, the wonderful things that
botany can do!
It
turns out that St. Peter’s Island was actually part of Berne, and the
authorities made Rousseau leave. He went back to being depressed. But years
later, he would look at his herbarium (pressed plant) specimens and relive his
erstwhile joys. I have done this also. I could not bring my specimens with me
to France, so I left them in university herbaria, as shown in these photos.
These specimens are: Acer macrophyllum, Alnus rhombifolia, Umbellularia californica (all from California), Rumex venosus (Nebraska), and Ipomopsis aggregata (Oklahoma).
“I
see only animosity on the faces of men, whereas nature always smiles at me,”
Rousseau wrote.
