How fascianting it all is. Not the least of which are the clinical experiments done in labs. Like shocking half the monkeys and rats when they ask for food, or depriving a monkey of his/her mother’s affections and offering it food held by wire or a cloth, and he/she chooses the cloth. The most fascianting part of those type of experiemnts is what it says about the human who can watch this and just note it on a clip board for a pay check. That the human seems to be devoid of empathy for others, or maybe just another species is truly fascinating. This would have to be tested with a human baby offered a wire held bottle or a cloth to know if the researcher then felt a pang of ethics. Or maybe the researchers own baby? Would they feel that was unethical to create such longing and lonliness in their own child or would the science anals be worth it? I’m sure you can find a scientist who could go so far as to mine orphanages in a 3rd world to experiement on fairly easily. Might be a smaller group that could deprive their own child a life of loving touch. The non human species is truly the most fascianting. No animal ever created a way to create suffering in another by depriving it love or sustenance just to see if it was as advanced as it felt it was. Animals eat, they procreate, they live in family structures and they clearly think and feel and they never experiment on other species with no empathy what so ever.
