Key Differences
Abstruse refers to concepts or ideas that are difficult to comprehend due to their complexity or depth. On the other hand, obtuse is used to describe someone or something that is not quick or sharp in perception, feeling, or intellect.
Abstruse and obtuse can both relate to difficulty in understanding, but the reasons for the difficulty differ. Abstruse difficulties arise from the inherent complexity of a topic, requiring advanced knowledge or thought to untangle. In contrast, obtuse difficulties stem from a lack of sensitivity or intellectual sharpness in the observer, making it hard for them to grasp even simple concepts.
While abstruse matters are often esteemed for their intellectual challenge and the expertise required to understand them, obtuse viewpoints or understandings are generally viewed negatively, as they indicate a failure to comprehend what should be apparent.
The distinction also extends to the emotional or aesthetic dimensions: abstruse art or poetry appeals to a deeper, perhaps more esoteric level of appreciation, requiring effort and knowledge to be fully appreciated. Obtuse reactions to art, however, suggest a blunt or insensitive capacity for appreciation, missing the nuances that give the work depth.
