Fact and Theory
Welcome back my brothers and sisters! Words are symbols that represent intellectual concepts. Communication depends on a reciprocal understanding and agreement on the relationships between words and concepts.
So if things are bad, how do we get by? The answer is simple. We have a marvelous reactive neural system for killing tigers (or each other) and solving the day to day survival problems, the tenacity for surviving harsh environments (be they social or climate) and enough of us have enough kids to more than make up for the losses (the excess children being another human idiocy). An intellectual creature by nature?
To sum it up: the human is a survival creature with a very weak intellect and a very strong set of instincts.
