I found this statement from Haanel (14-14) rather, well, odd.
It is therefore apparent that there is mind in every atom of the body; this mind is negative mind, and the power of the individual to think makes him positive, so that he can control this negative mind. This is the scientific explanation for metaphysical healing, and will enable anyone to understand the principle upon which this remarkable phenomenon rests.
His argument, if you haven’t read it, is that everything is built of electrons, which have a negative valence, and he then conflates negative valence with, essentially, pessimism.
I was confused until I did a little research.
Joseph J. Thompson discovered the electron in 1897. It revolutionized science.
Haanel launched The Master Key System as a correspondence course in 1912 and then formalized it in the book we’re reading in 1916.
While protons — particles that hold a positive valence, essentially balancing electrons — had long been theorized, Ernest Rutherford discovered in 1911 that a positive particle almost certainly exists, and then figured it out for sure in the years immediately following publication of Haanel’s book.
Haanel did live until 1949, so why he wouldn’t update the book with the new science at some point remains a mystery to me, but I suppose we’ll never know the answer.
But it is a good reminder to occasionally question and use your brain to find some answers.
