Definition: Abstruseness refers to a lack or absence of understanding, particularly in mathematics or philosophy where the concepts involved are complex and abstract. In mathematics, abstruseness can be seen as an inability to grasp the nature of something. For example, one might struggle to understand why a particular number, such as 13, is so special because it appears to have no inherent properties. On the other hand, another person might be able to explain why the square root of two (approximately 1.4) is an irrational number and thus represents a fundamental concept in mathematics. In philosophy or ethics, abstruseness can be seen as a lack of insight into moral or ethical considerations. For example, someone may struggle to understand how a person's actions are not based on logical reasoning but rather on intuitive impulses or emotions that cannot be easily explained by formal logic. In other words, the concept of "what is good" or "what is right" might be difficult for them to grasp. Overall, abstruseness refers to a lack or absence of understanding or appreciation of something abstract and complex in its nature. It can manifest as difficulty grasping certain concepts, difficulties with intuition, or inability to understand the deeper implications of moral or ethical considerations.
