Final answer:
A proper sensible is a quality sensed through one sense, while a common sensible is a quality sensed through multiple senses. A per accidens sensible is perceived indirectly due to association with another directly perceived quality.
Step-by-step explanation:
In philosophy, a proper sensible refers to a quality that can be perceived by one sense alone, for example, color is perceived by sight, and sound is perceived by hearing. Two examples of proper sensibles are the redness of an apple (seen by sight) and the sweetness of sugar (tasted by taste).
A common sensible is a quality that can be perceived by more than one sense, such as movement or shape. Examples of common sensibles include the movement of a car (which can be seen and heard) and the shape of a cube (which can be seen and felt).
A per accidens sensible, also known as incidental perception, occurs when something is perceived not due to a direct sensory interaction but because it is associated with something else that is directly perceived. An example would be recognizing a friend from a distance not by clear facial features, but by their distinctive gait or the color of their clothing, which one has come to associate with them.
