No arguments from me, because you are correct.The words you use: zygote, blastocyst, embryo, fetus… all of these are just words describing the stages the one single entity goes through, just as baby, toddler, tween, and senior describe stages the exact same entity goes through if the entity survives all the previous stages.
What you did not include in your argument is the difference between DNA, cell, tissue, organ and organism. These are also the different stages of development of the same entity, and yet they cannot be declared as “same”.
Also your argument is valid for all the entities. There is nothing special about “humans”. A chicken is functionally different from the fertilized egg. An acorn is functionally different from a sapling. Yes, the beginning - when the sperm fertilizes the ovum - is necessary, but NOT sufficient to declare a new human being. In my previous post I gave the reasons why, so there is no need to repeat it.
A tad incorrect. “Sentience” is not the same as “sapience”. The definition is “home sapiens” and not “homo sentiens”. But, of course, sapience is not an exclusive trait of humans. It is present in some form in other animals, the higher they are on the evolutionary ladder, the more of “sapience” is present.When we define human beings as having sentience (in the sense which differentiates us from other animals), we are not describing each and every individual human being. We are describing a quality of the species.
