Abstract: We suggest a new delooping machine, which is based on
  recognizing an n-fold loop space by a collection of operations
  acting on it, like the traditional delooping machines of Stasheff,
  May, Boardman-Vogt, Segal, and Bousfield. Unlike in the traditional
  delooping machines, which carefully select a nice space of such
  operations, we consider all natural operations on n-fold loop
  spaces, resulting in the algebraic theory Map (V_. S^n, V_. S^n).
  The advantage of this new approach is that the delooping
  machine is universal in a certain sense, the proof of the
  recognition principle is more conceptual, works the same way for all
  values of n, and does not need the test space to be connected.
