Are we of above Average intelligence? Is there a way we can make philosophy into a friendlier endeavour for the average guy?
Philosophy and critical thinking shouldn't be things someone either "has or doesn't have." We should all be equipped to learning and studying, and if it were more enjoyable for the lot of humanity, perhaps we would reach conclusions more quickly and thoroughly.
I am going to go from personal experience and say that I for one am somewhat intimidated by some philosophers and deep thinkers because I know that they have more knowledge on many subjects than I do. Perhaps this is silly, but alas let us not forget that the limbic system is in high demand. For someone who does not engage in deep or critical thinking on a regular basis, I can only imagine that they would be even more intimidated than I am considering their limited association with the process, and so my suggestion to limit this particular issue is simple... When you can... Dumb it down.
I know, I know, we have spent gobs of money buying the ability to create million dollar sentences, and while they are necessary in times in order to maintain specific clarity, they don't captivate society in a broad sense. If you can explain something in vast and great detail, so too should you have the ambition to reduce it to it's utmost simplicity. Of course this is not always easy.
I'm sure there are more ways to consider this question as well.
