" I have never had the feeling that I can control my will, and my perceived freedom of choice is (or at least feels like) a choice of acting on one will over another, not of choosing what to will. In fact, such a thing seems preposterous: what would influence me to choose to will, if not another will? (Or perhaps a meta-will, if you will.) "
It seems you have answered your own question within the question!!! But you would not have put it out here unless you wanted what some of us thought of it! So here are my two cents!
Someone in their answer above has mentioned three religions: Christianity, Judaism, and Islam. That prompts me to add some of the most ancient religions from East; Taoism, Buddhism, Hinduism, and several offshoots from the combinations of all the three in various forms. All of the above, in some form or the other, come to a conclusion, that "You" as you think of yourself, "do not exist."
The "I" or feeling of "I" is a temporary thing formed by accumulations of ideas mostly implanted by others, and the surroundings. ( so that "I" am different from the "chair" for example. ). So, in brief, when you say, " I have never had the feeling " - I would say, that is because that "I" does not exist in the first place!!!! and that is why you never had the feeling! That also answers the question that if there is no I, then, there is no question of "will"
But we are carried away with such ideas and examples as "where there is will, there is a way." And we can find thousands of examples to prove this to be right. But most often, these stories are right only in the hind sight. There are many more times more stories where the so called Will has not prevailed, but those stories get buried or not published. Mostly because no one wants to go to house tops and shout, "Hay, I failed, and failed miserably!"
In nut shell, it is becoming more and more obvious even from in science, that, there may exist nothing like "I" So what does exit, may be, for lack of words, be called, hmmmm, you can call whatever you like! Most people, when they cannot find the "I" revert to "You!" [ for example they will surrender and say thy will be done ]. But that is perhaps because of our (human) weakness not being able to comprehend something that cannot be defined in some form. So, many times, to use a language, they will say, the will of the Whole. Linguistically, that makes some sense.
There is no I, therefore, there is no will. Many times the word "will" is used in place of desire. Then, it is a different thing. Yes, desire exists! And it is a dream. Dream exists. It is Maya. It is play. (Leela). Those concepts are 'digestible.'!
Just want to make clear that I belong to no particular religion. I have mentioned them only as a historical background.
Thanks for giving me an opportunity to speak my mind!
