Final answer:
These artificial concepts are distinct from natural concepts as they are defined by specific rules or characteristics rather than experience or observation.
Step-by-step explanation:
Concepts which are based on definitions set by humans, for example, PRIME NUMBER, are known as nominal concepts. In contrast to natural concepts, which we understand through our experiences and senses, nominal concepts are defined by explicit rules or characteristics that have been invented. A prime number is defined as a number greater than 1 that has no positive divisors other than 1 and itself, which is a human-made definition applying a specific set of criteria to classify numbers.
Another example of a nominal concept would be geometric shapes, such as triangles or squares, which are described by a unique set of properties. A triangle, by definition, always has three sides and three angles. Similarly, the concept of artificial or artificial concepts is created artificially through our understanding and is based on specific characteristics that are always consistent. These types of concepts allow for a foundation upon which more complex thought can be built and communicated.
