These 3 sources of human behaviour appear to be similar to the 3 stages in my concept of Needs, Wants & Beliefs (my blogs).
My diagram to the right, also connects these 3 sources and 3 stages to the concept of Body, Mind & Soul (my blogs).
There seems to be a logical (time) direction and/or sequence, which is represented by the cycle of unhappiness, dissatisfaction and chaos (my recent blog).
After some reflection, I realised that this triangle must also have binding elements that prevent it from falling apart. These binding elements are another set of 3: Faith, Hope & Love (my blogs).
I must admit that my diagram is a little gloomy as it seems to represent an endless loop in human behaviour. There is, however, always an exit which I refer to as an/the Awakening (my blogs). The current general level of dissatisfaction and chaos suggests that we are somewhere at the top of the pyramid and that we need to make a choice.
Nowadays, Plato’s 3rd source of human behaviour, Knowledge, is turning into Beliefs, which are represented by my concept of the 7 Belief systems and its – again – 3 dimensions: Love (the 7th selfless belief – Emotion / Needs), Power (the selfish 3 beliefs of Money, Politics, Religion – Desire / Wants), and Knowledge (the selfish 3 beliefs of Philosophy, Science, the Truth – Knowledge / Beliefs).
Plato’s 2nd source of human behaviour, Desire, includes the Nature versus Nurture debate. British geneticist Adam Rutherford in Nat Geo, 14 October 2017: “There is a genetic basis to human behaviors. But there is also an environmental component. We used to say nature versus nurture. But we might say nature via nurture.  It’s perfectly possible for two people to have identical genomes and one of them to be schizophrenic and the other one not.”
I suppose that part of my writing is directed towards a human Awakening. This may also explain my regular use of a famous Albert Einstein quote: “Only two things are infinite, the universe and human stupidity, and I’m not sure about the former.”
A Gentle Awakening (2010) by JD McPherson
artist, FB, lyrics, video, Wiki
The people on the city streets
The farmers on the plains
They’re walking in the lucid dream
While the sky is set aflame
They soon will hear a quiet sound
So peaceful and serene
Then they might too may ease into
A gentle awakening
