No rules can be given for finding everybody's meaning.

The poets have their own way of expressing themselves; sophists, too, have their own way.

And the point often lies in what is unexpressed.

Thus, "barbarous nations make, the civilised write history," means that civilised nations do not make history, which none is so brazen as openly to assert.

Or, again, "Alcibiades is dead, but X is still with us"; the whole meaning of this 'exponible' is that X would be the lesser loss to society.
