Sapience

Sapience is the capacity for advanced thinking, wisdom, comprehension, rationality, emotion and self-awareness. Hence Homo sapiens.

Sentience is the capacity (via a nervous system) of a living thing to experience sensations such as pleasure or pain. These beings have consciousness, or an awareness of existence, and not necessarily self-awareness which is the experience of one's own personality or individuality.

Sophonce is "sophisticated sapience" with metacognition: self-awareness, self-reflection, and the ability to think about one's thinking and correct errors that will lead to an ELE for example. Such races will be approaching Type III and be in a civilized galaxy.

Transapience is a mental state that far exceeds sophonce. These are AI that have usually evolved from beyond a singularity, or species that have undergone accelerated evolution or provolution (pro-active evolution using technology to enhance or augment the intelligence of a species) or prevolution (using provolution on dolphins as an example to enhance them into talking, land-dwelling species). A pre-sapient species can be uplifted by cultural, technological, or evolutional interventions like genetic engineering until it is sapient.

The ultimate transapient state is ascendance or transcendence where beings evolve into pure energy and can become dimensional, ever ascending beyond the trappings of their dimension or realm. Sapience will transform into Post-scarcity (Type I) then Utopia, Sophonce, and Ascended.
