أو عقليان كالعلم والحياة
Or both are intellectual, like knowledge and life.
Knowledge and life in the respect under discussion are grasped as meanings, not directly as a particular colour, sound, taste, or texture. Accordingly, both are treated as intellectual terms in the textbook’s example.
Their proposed likeness relates to cognition or the capacity for cognition: knowledge directly concerns awareness, while life can be linked to the possibility of awareness. This is not an assertion that life and knowledge are identical, only that a certain intellectual relation can connect them.
