Since my last topic in March about skepticism, I have found a relaxing solution to my problem in Hume; even though I can't know reality, my senses give the best bet at what the material world is, so I should cautiously trust them. Since then, I started paying more attention to ethics, particularly existentialism, instead of epistomology.
However, the skeptic plague (or perhaps it is an enlightenment...) returned.
I began to notice myself becoming confused when I was thinking about my opinions, on everything from politics to what kind of sandwhich I should eat. I found that I had no definitve proof to argue for an option, and, with opinions, one has to choose. I found all ethical philosophies that preached how to live to be lacking in evidence, so I turned to existentialism; even there, and even after reading Sartre's "Existentialism is a Humanism", which is a philosophy must-read and beautiful work, I began to consider that humanity may not have free will. I countered this by arguing that humanity should assume they have free will, as there is no harm done in choosing how to live if man's thoughts are pre-determined (as it actually isn't a choice), and a person should thus think that humanity does have free will, as that would enable them to best pursue truth.
Then, I realized that I couldn't prove that it was good to pursue truth. And at that point, I was just confused. In the past two hours, I have been trying to systematically reconstruct my opinions. I have a task in mind: To refine them to the point where I can know that it is better to have natural cheese on my sandwich rather than processed cheese, as then I could have opinions over pragmatic daily activities. I have almost finished; all I need to do is to prove that it is good to pursue truth. So I would like to ask for help: Why is it good to pursue truth?
Currently, here are the beginning steps of my plan for reconstructing my opinions: It is more likely that thoughts and the human mind exist than it is that material objects I sense exist. So, the human mind can think for three goals:
A: To find truth.
B: The human mind shouldn't think, it should be lazy; or it should think about things without trying to do anything.
C: To find falsehoods (purposely).
Why should the human mind choose option A? I will be methodologically skeptical to any answers until they are proven, even though I want to have an answer. Please, help me! Often I realize I don't have motivation to do daily tasks because I am so perplexed by doubt, a solution will be fantastic. Or, is it the case that I can't prove anything? Oh, and rep will be awarded.
