SLI in my opinion. Clear preference for Ne/Si. He's heavily focused on a balanced, harmonious way of life, and strives towards this. Apt when dealing with sensations ("barley bread and water [can] yield the peak of pleasure"); has a clear concern about how best to treat sensations. This can all be related to Si. Has a philosophy which is evidently practicable, the main priority of which is to achieve happiness in the most efficient way, which is indicative of Te.
