Growing up, I often heard the phrase, “Blood is thicker than water.”
Maybe this is true, but which “blood?”
The current way we structure families in the United States–that is, what is called the “nuclear family”–has not always been the way families were organized.
There are, if you read anthropology, kinship arrangements such as: materilnial, paterlinial, and more.
In some cultures, what we know as “uncles” are the fathers. Thus, a child may have more than one real father. Likewise, there are cultures in which the woman chooses the husband and courts with him for a very long time before selecting him to live in her place.
So when one says that blood is thicker than water, what exactly do we mean? Is it that way in all cultures? None? If any, which ones? And does this thickness mean anything, well, good?
These are things I honestly do not know the answer to. Luckily, these are things that can be analyzed and scrutinized by people outside my discipline.
Philosophy? As we say: It’s brings branches of knowledge to life. As for those branches of knowledge? They may just be more rigorous, sound and truth-telling than philosophy itself. Philosophers, of course, don’t like to admit this, but that’s very much the way it is.
