General vs Particular

“But you must observe this, my dear Rodion Romanovitch, the general case, the case for which all legal forms and rules are intended, for which they are calculated and laid down in books, does not exist at all, for the reason that every case, every crime, for instance, so soon as it actually occurs, at once becomes a thoroughly special case and sometimes a case unlike any that’s gone before.”

Porfiry Petrovitch in Crime and Punishment by Fyodor Dostoevsky
