I would like to take one of buzzword's last three questions above and specifically address the two words extremism and violence and reframe them with the objective to:
1. demonstrate some natural laws at work in the universe removing cultural bias.
2. reframe the question in such a way which will remove any concept or notion of value such as "good" or "bad".
Once these ideas are understood in a different light, each one of us may come to a different conclusion than the one that they had before.
Let me start out with this saying; "As above, so below"
This saying is an old Hermetic phrase which refers to the correspondence of various levels of reality of the physical versus the mental (spirit) which relates to what happens on one level as happening on the other level. That is, what happens in the microcosm (the individual) is reflected in the macrocosm (universe) and vice versa and within each lies the other, and through understanding one (usually the microcosm) you can understand the other.
If you didn't follow that, don't despair, I will drill down further in order to elicit your understanding. Let's take the two words that buzzword and others have used before. The words are extremism and violence. Depending on your cultural background, education and other factors, thinking about those two words will probably agitate or irritate you or they may elicit feelings of hate, despair, anger and you may feel your vital signs change in terms of a rise in body temperature or increased blood flow and blood pressure.
The way that you think about those two words in the context of the discussions above will give rise to your internal representation of what you believe those words mean to you and at the same time, you will be reflecting on external situations that will have you feeling many different emotions. All of that is what is referred to as the microcosm or your inner world.
Now, let's look at examples extremism and violence in the external or natural world. I'm sure you can come up with many examples and I'm sure that your body will respond much differently. An example of extreme might be the coldest temperatures in the Antarctic to the hottest places on earth such as some parts of Africa or the Middle East. Examples of natural violent occurrence might be earthquakes, tornadoes and waterfalls. These are what might be termed as the macrocom or universe.
The natural occurrences can be reduced to a simple understanding of potential energy, kinetic energy, relative energy and rates of change. An example of this might be the evaporation condensation cycle which requires energy from the sun which in turn provides rains to fill the rivers which in turn allow water to fall in the form of a waterfall at an extreme and violent rate.
And, as an ancillary thought, that's why some worship the "Sun of God" or solar based religion while others are lunar based.
So, now I submit to you, if you understand the macrocosm or universe in terms of energy and reflect that back on the microcosm or internal world here are some potential answers to buzzword's questions:
Q1: "what can be done to interrupt the movement toward extremism and violence?"
A1: As long as there are differences (perceived, manufactured or otherwise) in culture, ideas, resources and money, that potential energy difference will eventually erupt into a release of energy in terms of violence and depending on what side of the fence you are on, that violence will be either detrimental to you or beneficial. This can also be termed in many different ways such as the difference of income levels or the "Haves and Have-Nots" and can be expressed in many other different ways.
There are millions of violent explosions in your car engine which are beneficial to you, but if a bomb exploded on you, you wouldn't be a happy camper. So, it's all relative and as the old saying goes, it's either them or me.
Am I fatalistic? No!. I'm a messenger, I am not making value judgments.
I am presenting the idea and notion for all of you to understand and realize that nothing ain't gonna happen without massive amounts of energy (mental, inner world). Great and profound mental energies can move mountains.
Marina's videos don't happen in a vacuum by lying on the couch. Marina expends an enormous amount of energy in order to publish a video. In order for Marina to do that there had to be a "will". I submit to you, that 99% of you do not understand the phrase "the will". (ref: 1% solution)
So, to answer some of the questions above, without "the will" and the mental energy to either neutralize, confront, or supersede other levels of mental energy, your notion of change will not happen. The greater the change in energy levels, the greater the violence. Change is guaranteed to happen as long as the sun shines, but in which direction it will happen is up to the collective us.
Part of the energy equation that I didn't talk about, but which is a reality is resistance and capacitance amongst other things. Real world examples would be demonstrations of electrical circuits and water circuits. In the inner mental world that refers to our mental capacity to endure and to offer resistance or our best efforts will be stopped by other resistance. And, so you may be asking how does one achieve that? Ask the opposition or perceived enemy, they are already doing it.
How else might I summarize what I said above? One can understand the natural world by learning to understand the "laws of nature" such as gravity for example. The natural laws are also reflected in the inner world of the mind or spirit. Many people have mastered these laws. Either one masters these laws or they will master you.
For further research into the macrocosm I might recommend Michio Kaku
where his vision of mankind's future considers terrorism one of the main threats in man's evolution from a Type 0 civilization to Type 1. Also, reference the Kardashev scale which is a method of measuring a civilization's level of technological advancement.
