If I take a philosophy class, I can talk to teacher, discuss things,explore questions and Contradictions. And I do :-).

When Plato says "let us all agree there exists a perfect blue independent of any real world blue", I want to argue that no, "blue" is a human construct and dependent on accidental biology. We can't even make sure thay we all experience the same blue and what "blue" is, is purely definitional. There exists no inherent "blue" other than us arbitrarily taking a chunk of EM spectrum and attaching a loose meaning of "blue" to it.

Plato did not know of EM spectrum or cones in our eyes. half the things he starts as "it is obviously true that..." I scream"no it is not! I challenge your key assumptions ".but he's dead and can't argue with me :-). So for me, that's not the whole point of reading Plato - it's the whole frustration.

Edit : you've added "that way you're exposed to Socratic method " which changes the gist of the comment, but I'll still argue it's a horrible way to do so. I understood Socratic method for a decade if not two before I tried Plato. If I tried Plato first, the dubious and implausible arguments would have turned me off completely. Both the teacher's and the student's proposals are frequently at odds with our current understanding, so as a reader I'm not invested in either and the argument feels farcical as opposed to logical.

My point is:

If somebody asks "what is Socratic method", pointing them to Plato is a horrible (and frankly elitist / gatekeeping) way to go. It can rather be explained in a few minutes with excellent, understandable modern examples. You can get working knowledge quickly and effectively. There are circumstances and situations where reading the original is relevant! But if you want to understand the basics, or even intermediate knowledge of actual subject, reading original newton and original Plato are not great ways to start.
