Yes, but you're neglecting the fact that you have to judge whether the proposition "modus ponens preserves validity" is true or false. That modus ponens is a valid argument structure is one of the background assumptions of our logic. Likewise, for our ethics we require some theoretical assumptions with regard to value before we can go about the systematic task of applied ethics. Modus ponens is not empircally determined but instead comes naturally to our internal logical apparatus. Similarly, the moral sense makes clear the animal Hierarchy and the central value of Caucasoids.HNAKXR said:modus ponens only affirms the validity of claims, not their truth.
Aristotle saw clearly that some 'men', by virtue of being of a barbarian race, fall naturally into subordinate hierarcy. I quote from book 1 of Aristotle's Politics:
"... [H]e who can forsee with his mind is by nature intended to be lord and master, and he who can work with his body is a subject and by nature a slave; hence master and slave have the same interest. Nature, however, has distinguished between the female and the slave. For she is not niggardly, like the smith who fashions the Delphian knife for many uses, she makes each thing for a single use, and every instrument is best made when intended for one and not for many uses.
But among barbarians no distinction is made between women and slaves because there is no natural ruler among them; they are a community of slaves, male and female. Wherefore the poets say, 'It is meet that Hellenes should rule over barbarians,' as if they thought that the barbarian and the slave were by nature one."
