CHAPTER XIII 
PLANT INTELLIGENCE 
“The Marigold goes to bed with the sun, 
And with him rises weeping.’ —Shakespeare 
T is no new thing to believe in the ex- 
istence of intelligence among plants. As 
far back as Aristotle, various great minds in 
the earth’s history have ascribed definite, think- 
ing acts to our floral and vegetable friends. 
Not a few have seen unmistakable evidences of 
soul in plantdom. Even the most skeptical have 
become aware of many things they cannot ex- 
plain in purely mechanistic terms. 
We are still living in an age which has 
deified human wisdom. Man has built up vast 
systems of knowledge and law, all based on his 
own deep-rooted convictions. He approaches 
every subject with apriori beliefs and presump- 
tions. He is slow to acknowledge thinking 
powers to his companion creatures of a ter- 
restrial universe.
