The primary qualities of bodies are intrinsic properties that are measurable and objective. In contrast, the antonyms of primary qualities are secondary qualities, which are subjective and dependent on human perception. While primary qualities include properties such as size, mass, and shape, secondary qualities include attributes such as color, taste, and odor. These qualities are not present in the object itself but are the result of our sensory experiences. Unlike primary qualities that can be measured and observed consistently, secondary qualities are subject to perception, interpretation, and subjectivity. Understanding the difference between primary and secondary qualities is important in fields such as philosophy, science, and psychology.
