These are three important terms that are very important in understanding the evolution of a Notion in Hegel's philosophy. Universal is an abstract that is extracted from experiencing numerous things. For example, fruit is a Universal, an abstraction. Nothing in nature can be found in the nature to be called a fruit; because what we call a fruit may be an apple, an orange, a banana etc. Universal exists as a mere abstraction. However, to speak more concretely, we have certain fruits. An apple is a fruit we define by its shape, color, content and other characteristics. But an apple, if we view more precisely, does not exist objectively because what we have is a red, yellow, green, sour, sweet etc. apple (Particulars), and even each of these classifications and concretization does not help the concept to get rid of universality. Therefore, everything Particular has a tint of abstraction. What is really objective and concrete is the one we immediately work on; the Individual.
