The article discusses the concept of 'substance' versus 'accident' or 'attribute' in philosophy. It explores how particulars are different from properties or attributes they possess. This debate is known as 'the problem of universals'. Different philosophers have taken various positions on this topic. The characterization of substance also implies a characterization of properties. Substance and attribute are related, so what applies to one also applies to the other. The study focuses on understanding the nature of these concepts and their relationship.
