I beg to differ.
A human only becomes what they're exposed to, what they learn through experiences. The moral guidance that is taught, becomes that inner guide to morality which is that little voice. The innate morals are only morals that have become second nature through repeated practice-reinforcement. Obviously bad behaviour will have negative consequences and so will deter a thinking person from repeating such acts; conversely, treating others appropriately will tend to produce 'good' results and reinforces those.
Inspired morals!?
I think the bible is what you mean here. And it is essentially the same thing as being taught to live in a way that was considered to be in accordance with "god's" wishes a long time ago. I call following this uninspired.
