that program. A program is a sequence of assembly language instructions. You have to enter the instructions into the xComputer's memory. But first, make sure that the "addr" input box in the Control area of the applet contains a zero. The number in this box specifies the address in memory where the instruction that you type will be stored. Then, type the following instructions into the "data" input box. Press return after each instruction (or, equivalently, click the "Data to Memory" button): lod-c 17 add-c 105 sto 10 hlt When you press return, an instruction is translated into a machine language instruction and is stored in the xComputer's memory. (You'll actually see a number in the memory, rather than the assembly language instruction that you typed. For example, the instruction "lod-c 17" is represented by the number 25617.) Note that when you press return, the number in the "addr"
Yet the two differ sharply in their logical properties. "I saw Martha" entails that I saw someone, while "I saw nobody" entails precisely the opposite; it is equivalent to "It's not the case that I saw anyone" and to "There is no one that I saw." Though someone just beginning to learn English might take it as one, "nobody" is not really a singular term, but a quantifier. In logical notation, letting A represent "saw" and i represent "I," "I saw nobody" is expressed as ~(x)Aix or, equivalently, (x)~Aix and the explicit inference rules governing this formal notation explain the logical behavior of the English sentence thus translated into it. So too, Russell maintained, the apparent singular term in (5), "The author of Waverley," is not really (that is, at the level of logical form) a singular term at all, but a convenient (if misleading) abbreviation of the more complicated quantificational structure displayed in (a)(c). As he puts it, the apparent
