The basis behind everything is philosophy. You have to start there. You sort out your philosophy and everything else evolves from that.
The philosophies I applied in my career were simple and basic. They stemmed from my upbringing, my beliefs and my experience. Above all my experiences in the world of education have added spice to my views. They are the same values I bring to all of my life: I did not need any religious moral code to arrive at it. It is pure common sense:
Everything should be fair
All people are equally valuable
Living things should be respected
Everything can be made better
Education should be fun and expanding
That is all. Everything stems from this; all the systems in the school; the way lessons are run; the way miscreants are dealt with – everything.
