Self-studying philosophy
I think that this is pretty good, and it lines up with my experience. I am an engineer who never had a hint of what philosophy was about until I had time - meaning retirement - to think about the big picture.
The way that I got exposed to philosophical notions was by listening to a history of philosophy via a set of audio lectures, which surveyed philosophical thought beginning with the pre-Socratics and going up to the present. From there I had a lot of questions I wanted to further study. I was not systematic, which means I was not efficient in my use of time. I just poked at this and that. And that’s all I still do, really. So it has taken a long time - years - for me to sort out a personal view of the world. Strong curiosity is a real asset to self-study success.
A point about the learning process: What I find similar about philosophy to science and engineering is the confusion of terminology/language. Every discipline has its own priesthood, which revels in obscurity. Fine, I get that. And I get the fact that there are deep and difficult thoughts going down any intellectual avenue. What is different is that in science and engineering there is the constraint of such things as experimental results and keeping the airplane in the air - exceedingly strong empirical underpinnings.
OTOH, a lot of philosophy is nothing more than sophistry wrapped up in big words that have obscure and personalized definitions. This makes it harder for the unwashed to wade through the nonsense and focus on the insights. Anybody who spends time with philosophy and really wants to get to the bottom of things, to achieve some clarity of thought, has to understand this and not be frustrated and give up. There are plenty of sources that make the important notions of philosophy reasonably clear, but it takes effort to find them.
