Sorry if there is so much that I leave out. It's too bad I'm too lazy to read Wittgenstein because I would be better at arguing that the problem of free will is a matter of semantic misunderstanding. I will go as far as to argue that most philosophers refuse to look at the elephant in the room since they make a living out of misunderstandings. Scientists make a living out of understanding each others well. Let's take again that "exact ground" thing. Now you have introduced the word "context". I mean, two humans cannot fundamentally find themselves in the exact same context. Even if we are in the same room when we hear something, I might hear the things being said just a bit louder and it get encoded in my brain more strongly, the words being used might have a slightly different connotation for me (how many words did you "know" from the dictionary only? None).

Let's say I tell you to imagine Obama wearing a sombrero. Well, I just did tell you. You cannot go back and unread it. Your brain just reconfigured itself to connect the "Obama" with the word "sombrero" in a closer manner. It also connected the current experience you are having - reading this text - with this new association. If in November you see a picture of Obama wearing a sombrero there is pretty good chance that the conversation will come back to your memory and it will have an influence on the moment your will be experiencing at that time. If you stop for a second and you pay close attention to your experience you will see thoughts arising in your mind without you asking for them. When you pay close attention, the speed at which thoughts and sensations arises and pass away is quite surprising. What is even more surprising is how random it is. Not only your consciousness is moving from your tongue, to your foot, to your hand, etc. in a random manner but you also have memories coming out of nowhere and you are like "What the fuck?".

The little exercise is this: put your finger like Mr Burns would do when saying "Excellent!". Close your eyes. Pay attention for a while to the tips of your fingers. It can pretty much feel like one unified sensation. Now, focus only on the tip of your thumbs long enough to have the sensation clear or more or less forget the others fingers. You should be able to do so to some extend, depending on your ability to concentrate. Now, do the same with the pinky only. Now, try to pay attention to both the pinky and the thumbs. Do it until you feel you are able to forget about the other fingers. Not only you will find it extremely difficult to do but you should experience quite fast (less than a minute) that your attention is in fact moving from the pink to the thumbs back and forth to create the illusion that you pay attention to both at the same time.

The good news about this is that a sensation isn't painful by itself. All our receptors works the same way and send electrical signals to the brain. Pain and pleasure is only our relationship in regards to those sensation. Do we have the desire for the sensation to last or to stop. Now, desire is something that exist only in the mind. During meditation retreats when you have pain you are instructed to focus your attention on the physical sensation. Since consciousness can only experience one thing at a time, you get only to experience the sensation, not the pain associated with it (That's why in Buddhism they identify 6 senses, the 6th being the mind).

I came to Buddhism because I was diagnosed with ADHD and developed a severe depression. I discovered that those guys were obsessed with attention. Attention is very different from concentration. Attention means that your senses are open, that you are aware, awake and willing to let enter into your experience whatever arises. While I used to try to concentrate, now I try to pay attention. From morning to evening. I just take note of where my consciousness just moved, one moment after another. As a exemple, while writing this message I pay attention to my fingers touching the keys, the sounds of the cars outside, the pain in my back, the saliva in my mouth, etc. While writing it's not so easy to pay attention to thoughts arising be it's not too hard when doing activities that doesn't requires too much brain power. While all doing this I can relax my muscles and just enjoy the ride. The problem is when the mind start to tell me stories. I can be anxious about something, as an example. I then loose touch with the present moment. Because that's what this is all about, the present moment. The mind live outside the present moment. We suffer when we are out of sync with reality. So the process of life is basically reality trying to synchronize with itself. The next time you feel the desire to have sex (or eat Doritos, there is not difference) pay attention to your experience. There is somewhere in your body a sensation that you want to end. At the same time, your mind is going in every direction. You are going to do so by stimulating a small area of your body and force yourself back into the present moment. You will feel relief. For a while. The cycle will restart just after that.

Once you have made the connection between the mind and suffering and have realized that we never experience a moment of pure satisfaction, you are fuck man. You are completely fuck. No amount of entertainment will distract you from that reality. You have to chase the present moment one moment after another until you get there.
