Everything you do is caused.

We don't have freedom to be free, that's a tautology. We always act and behave according to our circumstances, whether as the immediate occurrence (what happens right now), or as a product of prior experience or conclusions (what is contained in memory as a footprint of the past).

The only way the freedom exist, is in the ability to perform actions and behaviors, that concord to previously constructed model of values, as opposed to necessity to act and behave contrary to that model, being forced/coerced to follow someone's model or your own lower-degree faculties (instincts).

Is it very clear? Not at all. Consciousness is something the brain does. The brain and all of its states are caused. The brain was caused to exist and all of its limitations and abilities with it. All determined by factors before it came to exist. Each choice that brain makes are all constrained by its makeup.

If consciousness existed despite a brain then brain damage wouldn't have any effect on anyone. The living, functioning brain is, for all intents and purposes, consciousness.
