Aristotelian = of Aristotle. Aristotle believed that regular reading, research, and expansion of the mind on various subjects was necessary to a good life. He wrote a great deal about the good life. I suggest adding that to your reading list.

I just take a subject say, "Scoliosis" and just put that into google and see what comes up. I start with the most popular sites and then look to more personal accounts once I know what is or is not scientific about it. For example, I am working on a novel right now and I needed to know how people performed check fraud. So I put that into google and started to read and eventually found a book by a detective about different cases he had solved. That helped me create a scenario that was very good and real life for the book. If you so choose you can do that regularly on a variety of subjects to learn more about something. The luxury about having a background in classical languages is that you can decode language and derive some meaning from it. Research is about layering. You start at the surface and then go deeper, then deeper and then deeper still. Think about the hierarchy of media:

Social Media (instant) Newspapers (or daily up to the minute news) Magazines (or media taking 4-5 days to create) Content aggregators/Monthly Publications Books

So for example researching check fraud I might see:

Tweets/posts about it A newspaper article about a check fraud ring A Magazine piece about its prevalence in America A group of these items over a period of time between one month and one year A book about check fraud rings by an expert

How far you go in the hierarchy depends on how much you want to know or where that information might be located. Also, for more effective searches in the future you may wish to use full sentences (Google is getting good at that) or also learning Boolean search terms.
