For some, original sin is the best way of talking about ineluctable human limitations and is of real value
something we might hail rather that decry.
Even in its secular version, say of anti-social behaviour it is that burden we carry on our shoulders and it is better there than not; for this little knapsack we carry might be a reminder of our human limitations and aspirations.
Writers through the ages from Icarus in Greek mythology up to the modern send out restraining messages
we seem not to be able to do without it whether as something to be acknowledged or as something to be defied.
The notion of original sin is remarkably resilient, rather than a problem it might be viewed as a burden that aids us.
