Dictionaries are very terse on the subject, and I don't really know where else to look. English.SE closed my question as too opinion-based, I can't blame them really. The words don't seem to be very firmly defined, so I'm not even sure if a simple answer to it exists, but if it does, I guess here is where I'd find it.
Able to perceive or feel things
- formal Wise, or attempting to appear wise
1.1 (Chiefly in science fiction) intelligent
.2. Relating to the human species (Homo sapiens)
Can a hypothetical entity be sapient, while not sentient?
My particular line of thought went this way: Humans develop an AI which is fully sentient and sapient, along with our understanding. Then we develop a derivative model, specifically deprived of features that comprise sentience, while not restricting the "intellect" part:
- no initiative - only reacts to commands, is dormant upon completing them. No such thing as boredom, compulsion to act for lack of action alone.
- no curiosity - is able to obtain external information or learn (in a broad meaning of the word, not just new entries of specific data but also entirely new domains or methods of processing), but only selects what is necessary to complete the task, has no compulsion to obtain any unnecessary (at given moment) knowledge or skills.
- has no emotions of its own - can process emotions of humans as facts in inference process, but never internalizes/shares them, treating them as simple modifiers of expected behavior of others.
- has no desires - beyond the preset goal of fulfilling commands, doesn't attempt to change anything about itself or the external world.
- no specific self-awareness - the database contains entries about its own model, its own properties, functions and capabilities, but it doesn't bear any special meaning beyond "these are resources that can be allocated to commands given"; treats 'self' as another entity in the greater image of things, along with all other entities equal or graded by any required metric with the property 'this entity is me' being of zero significance.
Such an entity would be able to think - conduct inference, come to logical conclusions, learn, understand feelings, influence feelings of others, and lead a fully meaningful conversation providing initiative of the other party, but otherwise lacks basic features of a sentient being.
Did I disbar any features which are essential to sapience, or is there something that would still make it sentient? Or otherwise, is some other sapient-but-not-sentient entity possible?
