At around 4 minutes into the September 2015 video Splane said "For the man and the baby to be part of Josephs generation they would have had to have lived at least some time during Joseph's lifespan."
This is the lynchpin of the WT argument, that two lives must overlap to be considered the same generation.
Let's take an example of twins who are born just a few minutes apart. Obviously, these twins are the same generation as each other. Then the twins grow to old age.
If a baby is born between the first twin dying and the second twin dying, that baby is not considered to be of the same generation as the first twin, only the second twin. That's just stupid.
Let's take the example that Splane used, Joseph and his brothers. These are the same generation as each other.
Joseph has an older brother. They grow old.
If a baby is born after Joseph dies, but before the older brother dies, the baby is said to be of the same generation as the older brother, but not the same generation as Joseph.
This is a nonsense. The baby's life overlaps with an older person than Joseph so how could this NOT be Joseph's generation too?
What Splane is doing is trying to obscure the distinction between a generation and contemporaries.
You can be of the same generation even if you are not contemporaries.
A child dies at the age of 8.
Another child is born the day after the first one dies.
They are not contemporaries but they are the same generation.
Splanes explanation above would have us believe they are not the same generation.
My brother is 50 years old. I am 40 years old.
If I die tomorrow and my nephew is born next week, my nephew is in the same generation as my brother, but not the same generation as me because our lives do not overlap, yet my life was within my older brothers generation.
Sorry GB, you need to try harder to explain the unexplainable because after years of effort and word twisting, it STILL does not make any sense.
