A paradigm is the framework that an individual uses to make sense of some part of the world.
If you notice, for the first time, that a) when you eat a lot of sugar b) you seem to feel a lot of energy, you will try to explain the connection between those two events in your mind. Depending on your history, and other factors, here are some possible paradigms you might come up with.
1) The Magic Paradigm. Maybe when you eat sugar some genies magically energize you.
2) The Drug Paradigm. Maybe sugar is a drug that causes you to release energy.
3) The Energy Paradigm. Maybe sugar is energy, so the energy you feel is not from you but from the sugar.
For the vast majority of people, important paradigms are derived from a group.
Every group a person "belongs to" will have some influence on which paradigms that person uses. Groups can be put in all sorts of categories, but for the purpose of defining paradigms, there are basically two kinds of groups, natural and artificial.
The ideal progression of an individual, through groups, is roughly as follows.
1) The individual is one part of a family (i.e., a child, a sibling etc).
2) The individual is one part of "half of society" (i.e., male or female).
3) The individual is one part of a family (i.e., spouse, parent etc).
(and so on)
The extent to which an individual joins a group that takes awareness from that individual, new paradigms will be necessary.
