Final answer:
Nominalism, the position that denies the existence of abstract entities like numbers, was once prominent but is not widely accepted in contemporary philosophy. Arguments against nominalism include the disconnection between beliefs and evidence, as well as the difficulty in proving general negative claims.
Step-by-step explanation:
In philosophy, the debate over whether numbers are particulars is a topic of discussion. Nominalism is a philosophical position that denies the existence of abstract entities, such as numbers. While nominalism was once a prominent position, it is no longer widely accepted in contemporary philosophy. There are several arguments that have been put forth against nominalism, including the disconnection between the truth of beliefs and the evidence used to support them, as well as the inability to prove a general negative claim. These arguments have been deemed compelling in challenging the validity of nominalism.
