Causative Conation: Potentiality

Halliday & Matthiessen (2014: 582):
Here there are causative forms as follows:
(1) potential: the patient can see clearly
(caus.)           this enables the patient to see clearly 
(2) achieval:  John learnt to fly
(caus.)           Mary taught John to fly
Again, these causatives have passives: the patient is enabled to see clearly, John was taught to fly by Mary.
