F.H. Peters

A man may do something grammatical [or write something correctly] by chance, or at the prompting of another person: he will not be grammatical till he not only does something grammatical, but also does it grammatically [or like a grammatical person], i.e. in virtue of his own knowledge of grammar.

Thus anyone can be angry—that is quite easy; anyone can give money away or spend it: but to do these things to the right person, to the right extent, at the right time, with the right object, and in the right manner, is not what everybody can do, and is by no means easy; and that is the reason why right doing is rare and praiseworthy and noble.

Now, praise33 or blame is given only to what is voluntary; that which is involuntary receives pardon, and sometimes even pity.
