تُدْرَكُ بِهِ الْغَائِبَاتُ بِالْوَسَائِطِ، وَالْمَحْسُوسَاتُ بِالْمُشَاهَدَةِ
Absent things are understood through intermediaries, and perceptible things through observation.
Here “absent” need not refer exclusively to the theologically unseen. It may simply mean not directly present to the senses. Smoke, for instance, may prompt an inference about fire; a trace may disclose a past event.
Senses provide certain inputs, while reason can connect them to further conclusions. Neither all sensory experience nor all rational inference should be rejected merely because the two have different functions.
