A dynamic and ongoing way of coming up with answers, rather than a static and solitary answer. As
@linebaugh says, yin/yang is the most intuitive example of this, in my opinion.
I think of it as a way of mapping though, rather than the actual orientation of universal forces irrespective of our conception of them.
In giving an account, in making a decision, stating a thesis, etc, its seems one is necessarily being partial, no account is a full account, etc.
So the dialectical method is a way of incrementally mitigating this partiality, by giving an account/thesis, then identifying what that thesis doesn't account for and creating an antithesis around that, then synthesizing them to account for as much of both as possible, namely the synthesis, which is still partial and can have yet another antithesis formulated in response to it, and the process can go on and on.
Its well suited for multiple people, for
words between people.
DIdn't know that praxis mean't applied thesis/theory though, I had just assumed it was greek form of practice.
