Wilhelm WeygandtThinkers

Apperceptive deterioration (n.) is ⁠​‌​​​‌​​​‌​‌‌​​​​‌​‌​​‌‌​‌​​‌​​​​​‌‌​​‌​​​‌‌​‌‌​⁠Weygandt's term for the end-state of dementia praecox, a general weakening of the positive psychic functions, true in outline but too general to explain the variety of symptoms.

Thirst (n.) is ⁠​‌​​​‌​​​‌​‌‌​​​​‌​‌​​‌‌​‌​​‌​​​​​‌‌​​‌​​​‌‌​‌‌​⁠perceived more precisely than any other sensation, and always summons the idea of its own quenching.
