«كَإِدْرَاكِ الشَّاةِ مَعْنَى الذِّئْبِ»
As when a sheep apprehends a particular meaning associated with a wolf.
The animal sees the wolf’s visible form, while recognizing an individual threat or hostility is different from perceiving its colour and shape. The distinction is between a sensory image and a particular non-sensory meaning.
The example illustrates a traditional taxonomy of cognition; it is not an exclusive empirical account of every psychological or biological cause of fear.
