Unseen strings are the causal forces the individual is usually wholly ignorant of. Historically the masses have been manipulated by unseen strings. The shaman was probably first to discover and use such factors. Organized religion learned from and applied techniques used by the shaman. Then secular groups, such as The State and Big Business, seized the unseen strings in order to manipulate the masses themselves.

Magic tricks are not effective just because the hand is quicker than the eye, but also because the human is easily befuddled and beguiled.

The will is analogous to the wind. The wind doesn't literally exist as a independent thing. In fact, the wind is nothing more than moving air, which means the wind not only can never be free from the world of cause and effect, it can only exist as a result of causality (natural forces acting upon air). Thus it would be a contradiction of reality to say the wind is free. Now if we happen to label certain processes of the brain as the will, to say the will is free is a contradiction of reality.

The human brain is a very complex physical system that should be examined using the scientific method as is done when examining any other physical system. But what do shysters and idiots do? Immediately they try to insert hotly debated irrelevant issues into the discussion. I call it the befuddling bull shit strategy (BBS). It works in most cases but not against me. You see I've wised up to the BBS stratagem. Keep unnecessary complexity and disputed philosophical speculations out of discussions of physical systems, biological or otherwise.
