No such thing as free will
Free will is a construct of concepts.
Reality is we all do what we do when we do it - in connection with survival instincts.
There is nothing we do, that is unrelated to nature. Everything can be traced back to an active survival instinct.
In that sense, there is no such thing as "free will" - but it is also the only kind of will we have. So IF we are to call something "free will", when we are to synonymize "instinct" with "free will".
If so, we do have "free will", we just call it many things, among them "survival instinct"
And before someone challenges my statement:
Playing tennis - proving your physique - attaining a mate - survival instinct
Eating a snickers - energy consumption (sugars and fats are highly valued) - survival instinct
Watching tv - natural curiousity for new impressions - consistent with an oportunistic lifestyle - exploring new regions/foods/methods - survival instinct
Masturbating - ... ok, you got me there.
