Definition

Adjective: 1. (Of light, sound, or other waves) Not bounced back or redirected by a surface. Specifically describes a wave that is absorbed by or passes through a material rather than being reflected. 2. (Figurative) Not thought about or considered; lacking conscious consideration. This meaning is less common and often used in psychological or philosophical contexts to describe thoughts or impulses that are not subjected to introspection.

• Philosophical Context: Can be used to critique ideas or actions that are accepted or performed without critical examination.
