If the government has complete and absolute power over the people, that's totalitarianism. This is a repressive, unfree type of society. A democracy is a society in which people have a say in their government and elect their leaders. The opposite is totalitarianism: a totalitarian society is usually ruled by a dictator, and there is very little or no freedom. In totalitarianism, the government controls almost every aspect of life. There is no free speech or freedom of the press: certain religions and ideas may be banned. George Orwell's novel 1984 was a brilliant look at a world of totalitarianism.
An additive process is one in which something is added to the art piece to give it interest. A 2-dimensional additive process is painting, you add more paint to the canvas. A 3-dimensional additive process is coiling a clay pot, you add more clay.
You might say, Art is in a constant state of change, so nobody can really pin down what it is.. The constant change part is true, but the not pinning it down part is an evasive answer. Don't go this route. You might even say Art is subjective, and means something different to every single person on earth.. This, too, is the truth. I would caution against this definition, however, as it would require a stack of paper from here to the moon to cite all of your 7.4 billion references.
