Ordinary language is all right.
One could divide humanity into two classes:
those who master a metaphor, and those who hold by a formula.
Those with a bent for both are too few, they do not comprise a class.
'At the beginning of the Hellenistic period (ca. 323–31 B.C.), Greek society enjoyed the refinements and luxury of a highly developed civilization, yet social inequalities were always widespread. It is often asserted, and with some justification, that with the decline of the polis (or city-state) as the comprehensive center of social life, each individual felt compelled to secure his own happiness in a world in which it was not uncommon to be sent into exile, taken prisoner by pirates, or sold into slavery, according to the whims of Fortune (Tukhē). From this point of view, Cynicism was intended as a response to this quest for happiness, by which the Greeks of this uncertain time were almost obsessed. Consequently, it offered Hellenistic society a systematic moral practice (tekhnē) capable of guiding the individual toward happiness and delivering him from anguish.'
Cynic freedom: 'To use any place for any purpose'.
