> If you are asked to pick your favorite philosopher, you will have a few names pop into your mind, but you will not have control over those few names.
Free will is not about choosing what comes into one's head after sending an inquiry out into the universe, it is solely about what we do with our physical body. That is part of why choosing to focus on the highly cerebral work of programming is so difficult.
> because the decision to do so is the sum product of all the things that have happened to me
So a three-pack-a-day smoker cannot quit? A lifetime racist cannot jettison those beliefs and choose to understand the truth that we are all just human beings? A believer in selfless love cannot become a child molester or otherwise oppress others?
Inertia in life is very, very real, but we each have the power to change. You could even accept the truth of what I say. We are not mechanical machines driven by the past; our wetware is impressionable but not fixed, as it is "wet" -- i.e. fluid -- and we can either continue to flow into the ever-present now, or merely ossify into preset patterns. That is why curiosity and humility are so important to becoming an intergrated human being tuned to positivity. No, we are not born at such a level, for we are each somewhat selfish from go; we must choose to learn how to be such a person, and then choose to do what it takes to become such a one. Yes, it is difficult in this selfish world of myriad physical/mental/emotional pollutions, but having such peace and happiness makes it not only worthwhile, but indeed the only path worth choosing, always. As the wise Bob Marley said, "Those that feel it know it not." And yet we live in a world where people run away from the truth. Those that taste the fruit of all-consuming selfless compassion never shy away from plucking another grape from that vine.
> If I choose to give money to the next homeless person I see as a result of this comment, it was not free-will, but the sum of all of those things and my response to this comment.
But you must still choose to do such loving service, at the time the opportunity presents itself. In those moments, once your mind presents you with the possibility to manifest generosity, you must engage your free will, reach into your pocket/wallet, and give the money. It is solely up to you, and that is the truth of the fact of the matter, as is the fact that the ignorant love to follow the ignorant, because it makes them falsely feel that they are superior to the wise, which is not only silly, but commonplace. Dunning-Krueger is yet another sadass gospel of truth.
> The will of the homeless person is also not free, the knowledge of which should expand your compassion for them as their situation is not the result of an endless series of bad choices, but the unfortunate chance outcomes of their existence in this environment.
I don't care how much their choices have caused their dire situation (although I fully agree that society's cruel callousness is more than likely the dominant cause of their predicament, as it is with nearly all of the world's poor). My decision with regards to how I treat any person is my choice and my choice alone, and the karma I earn for my action or inaction is mine alone to bear and has no bearing on their choices, only their happiness. We are each an island of choices made in a flowing sea containing other islands.
Further, I cannot will myself to be a billionaire and thus manifest crazy generosity. No, my free will must work within the constraints creation has placed upon me. All I can (choose to) do is be the most compassionate I can in every situation, given the opportunities presented to me, with the resources I have available to me, and, hopefully, in the way that is best for their situation. It's all any of us can do, understanding that we are only responsible for our choices, not those of creation, itself.
Choosing wisely requires us to first understand that we are continually choosing, and that such wisdom requires honest self-evaluation, exploratory learning, and effortful practice. One's happiness and peace is the universe's feedback mechanism to our choices (though our polluted/stressful environment can cause physical depression and other mental/emotional difficulties, too). Put another way: inner peace and happiness is the only important dashboard instrument on one's journey. Helping reduce others' misery, or otherwise increase their happiness, is the most important path to our fulfillment, as we are all in this together via the karmic equivalent to the Universal Law of Gravitation. It's the most sublime law of creation, operant only for we human beings, the only possessors of free will and a self-tunable moral compass.
