OK first to the perception of "the present". We must ultimately concede that the term "present" is a subjective word, and not objective. For further clarification I'd refer to the ancient greek story abou the rabbit and the tortoise. (demacules was it?) If the turle started first, but the rabbit was faster, the rabbit would never win the race because the distance between the 2 would be broken down into halfs in infinite increments, so the rabbit would never win, if we broke time down in the same way( I may be off on the details, but you get the point.) So this has all been discusses and agreed upon.
As to free will- It does not exist. It is an illusion. tea or coffee. He chose coffee because he had coffee that morning, and because he's had coffee 16 times over the past 3 weeks, and had tea only once. And because he prefers the taste of coffee. And because his wife hates it when he drinks tea. And because coffee is first on the menu, and because tea gives him gas.. and on, and on and on.
People try to equate the inequities in the decision making process with free will, when in actuality, it merely comes down to things that we haven't taken the trouble or time to gauge yet. The gaps between the thought process and the actual choice do not actually exist. There is a process which leads us to sucessfully make a choice from all our selections. It's based on our past actions, beliefs, experiences, thoughts, and actions. He would have inevitably chosen coffee. To know all thought processes leading up to this decision is to know and predict the future. It's like gambling without the risk.
Consider this: Everything that we are is casuality. Free will claims to be a drop of randomness amongst a see of order. Let's consider this. We as human beings have evolved through a natural process of ordered selection. Our physical makeup. Including our brains. Our thought processes, our behaviors, our decisions, all have roots in basic human instinct. At the root of it is ID EGO, and SUPEREGO, controlling our lives, our minds, our choices. Sure, we have a higher thought process that gives us the illusion that we are making free choices. But not before the old ID, EGO, And super ego gives it first level clearance. And those are subconscious processes beyond our control. We don't even percieve of them most times. Like the fight or flight response. The survival instinct. That's why so many find it so difficult to sacrifice their lives. It's the battle between the subconscious self preservation, and the higher brain function telling us that we have to kill ourselves to save many more lives, etc. And the same applies to our normal every day decisions. Like the study on how we have already made a decision a split second before we react to that decsion. It's all been decided, we just haven't gotten the update yet. It's all a matter of perception. And free will is a matter of perception of reality, and our understanding of the process. We percieve our decisions as something that isn't static because we lack the undestanding of all the variables that go into the making of each decision. If we did, we'd see that there is actually order in what we percieve as chaos
Or at least that's how I see it
