Scientifically speaking, the purpose of life is to make babies and ensure that they have babies in turn.
This is our legacy.
But so too can our memes reproduce, recombine, and perpetuate themselves long after we’re dead.
Because our behaviors, impressions, and ideas are not easily tangible or measurable they tend to be relegated to the realm of things that are subjective and more or less unreal much like art, beauty, or meaning.
But consider a man who has fathered a family but cannot relate to his own children. He has succeeded genetically, but failed utterly to pass on his world view, his perspective, his memes to the next generation.
In a way, his flesh lives on but his mind and very soul perishes. And as many a father has found, there is something nightmarish in this.
Let’s also consider the great luminary who leaves behind no children but creates ideas that echo through the centuries.
Their spirit lives on, but their ideas are twisted by the great majority who do not have it in their nature to understand.
The greatest ideas accomplish little if there are not those of the right flesh to receive, understand, and enact them in subsequent generations.
I would suppose then, that a complete legacy is both genetic and memetic in nature?
