  This paper has two main parts. The first one presents a direct path from
microscopic dynamics to Debye screening, Landau damping and collisional
transport. It shows there is more simplicity in microscopic plasma physics than
previously thought. The second part is more subjective. It describes some
difficulties in facing plasma complexity in general, suggests an inquiry about
the methods used empirically to tackle complex systems, discusses the teaching
of plasma physics as a physics of complexity, and proposes new directions to
face the inflation of information.
