Now I was it to know about rhetoric in the same way;-is rhetoric the only art which brings persuasion, or do other arts have the same effect? I mean to say-Does he who teaches anything persuade men of that which he teaches or not? He persuades, Socrates,-there can be no mistake about that. Again, if we take the arts of which we were just now speaking:-do not arithmetic and the arithmeticians teach us the properties of number? Certainly. And therefore persuade us of them? Then arithmetic as well as rhetoric is an artificer of persuasion? Clearly.英文原著 · 《Gorgias》
This is obvious, whenever we undertake to apply the processes of arithmetic to the realities of life.

Such a system of money-arithmetic would be entirely unmanageable for the common purposes of society. I proposed therefore, instead of this, to adopt the Dollar as our Unit of account and payment, and that it's divisions and sub-divisions should be in the decimal ratio. I wrote some Notes on the subject, which I submitted to the consideration of the financier.英文原著 · 《AUTOBIOGRAPHY》
