``In almost all textbooks, even the best, this principle is presented so that it is impossible to understand.'' (K. Jacobi, Lectures on Dynamics, 1842-1843). I have not chosen to break with tradition. V. I. Arnold, Mathematical Methods of Classical Mechanics [5], footnote, p. 246

It's funny that this quote is not ironic at all, and in fact the authors of SICM include it because they agree with the assessment (by Arnold of his own textbook and its predecessors).

The SICM authors do indeed break with that tradition.
