its ok to be a sociopath or narcissist because what DON'T feel you will make you the strongest person in the room next to Silent One

the concept that all life is important for other life to exist and it isn't infinite

Reality, the main thing anyone in a religion is in clear avoidance of.

The importance of lovingkindness in our dealings with each other.

To pay it forward, not pull the ladder up behind you. If you're doing well, or just okay help someone get up another rung. I remember Rubio's speech a while back. He mention cutting aide to people in need. some of the things he suggest to cut were, health care, food stamps, and college tuition. This pissed me off because he used all of these to get where he's at.

I would be tempted to teach everyone the Jacobs Brain Speed Quotient and how to maximize it. With it, everything else will be much easier, and quieter.

Jacobs Brain Speed Quotient: The speed of the brain is inversely proportional to the speed of the mouth in words per minute multiplied by the volume in decibels squared.

Sb = 1 / (Sm * Vd) ^ 2

The concept that everything is a concept.

Mortals are on their own. There is no Authority greater than nature. That it only comes once
Is what makes life so sweet

Empathy. Truly understanding others point of view and basing decisions on that understanding would help in so many ways. Reduce hate, racism and genocide, as we as things that cause hurt and pain to others.

The total happiness within a society varies as the sum of the log of empathy of the individuals in a society. Basically, the Golden rule, but in math terms so that you can get more happiness in a rational and orderly way.
?(i=1)^(i=n)??log?(e)= ??(i=1)^(i=n)??h??

One word: Enough. The constant greed for more, more, more rots us to our core.

Tolerate each other. You don't and won't like every person you meet, but if you can tolerate them and they can tolerate you, our population will explode and we will all die. Always look on the bright side of life....whistling...

The process of Evolution. The details include enough science to bring them up to speed on that, and the implication of evolution, the continued change of life, would frame our place within the realm of everything, both before and after ~

Empathy

Empathy.

Live your life with compassion, understanding, and empathy for those around you.

SKDeitch already said "critical thinking," so I'll say "art appreciation" because I think art (of all sorts) enriches society and makes life more flavorful.
