There are “machine men” - those who ignore or shut down their feeling nature and “feeling men”- those who feel and act on their feelings, when appropriate.
Almost all the terrible things that happen in the world- to people, animals and mother earth- happen because of machine men.
The intellect, acting alone, is a dangerous thing. Only when coupled with the feeling nature, which opens us up to the experience of others and to our own empathy and compassion, are we likely to act in ways that are harmless, both for ourselves and others.
Some people shut down their feelings in some domains of their life while allowing themselves to feel in other areas. This allows them to be destructive in one domain while constructive in another. This leads to a divided man and is not to be recommended.
I believe we were born with a feeling nature for a reason and that is to encourage us to act in ways that are beneficial to creation as a whole rather than just suiting our own limited mental concepts.
When we ignore our feeling nature destruction is the result. This can be seen in all the violent acts that occur on the earth against other people, animals and the planet itself.
Many of these actions are viewed as "necessary" but this is only because those that carry them out or condone them are deluded by distorted thinking and have shut down their feeling nature which would tell them these things are wrong.
This denial of feeling makes these people a danger to all life. We must regain our connection to our feeling nature and act according to its dictates (in conjunction with our rational nature) if we are to become noble co-creators on this wonderful planet.
