 Section 1 will describe the contemporary platonist view in detail. Section 2 will describe the alternatives to platonism — namely, conceptualism, nominalism, immanent realism, and Meinongianism. Section 3 will develop and assess the first important argument in favor of platonism, namely, the One Over Many argument. Section 4 will develop and assess a second argument for platonism, namely, the Singular Term argument. This argument emerged much later than the One Over Many argument, but as we will see, it is widely thought to be more powerful. Finally, section 5 will develop and assess the most important argument against platonism, namely, the epistemological argument.
