It is human nature to follow along with what others are doing. This is pleasantly referred to as being sociable, cooperative, and getting along.
A darker side of that is called herd mentality. The side of humans that continues to be very destructive: millennia of wars, detonating thousands of nuclear weapons, leaks from nuclear energy facilities, the sixth great extinction, thousands of years of human rights violations from superstition and nationalism, greenhouse gassing ourselves into climate change and ocean acidification, and worsening these issues with overpopulation.
A major factor in why we continue to be so destructive, is it is also part of human nature to be poorly informed and apathetic on major issues. And when we are poorly informed of facts, principles, and ideas, we instead default to merely going along with large groups of other poorly informed individuals. Such as religions, sexual superstitions, nations, and their political parties and militaries.
Instead of widely reading non-fiction, humans overwhelmingly prefer entertainment. This is where The Arts come in: they are a way to insert awareness, education, human rights, big ideas, intellect, environmentalism, and other human progress into various entertainment mediums with emotional impact to a receptive audience.
A paltry few of myriad examples of The Arts enlightening and furthering humanity: Comic Relief fundraisers to change the lives of the poor, the We Are The World song raising money for African famine relief, Earth Song (environmentalism), the Same Love song (= rights), or Charlie Chaplin’s The Great Dictator movie and Pablo Picasso’s priceless Guernica painting both making a stand against Hitler.
So at their best, The Arts are a lot like sneaking little bits of vegetables into the foods we know children prefer to eat;-].
