النَّارُ حَارَّةٌ
Fire is hot.
The example treats awareness of heat as connected with sense perception. Other examples include seeing a color and hearing a sound under suitable conditions. An accurate judgment also requires knowing the circumstances of observation and the specific property being perceived.
A distant object may look blurred; a straight object in water may look bent; the appearance of a color may change under different lighting. Such cases invite us to distinguish an appearance from an inference about the external object.
Recognizing the senses as genuine sources of knowledge does not imply that every sensory impression or every judgment based on it is infallible.
