?The PD is a science fictional projection of the naturalistic fallacy and injunctions against playing God. It's also a disturbing application of social Darwinism. The underlying assumption of the PD is that a civilization must attain space faring capabilities and advanced technologies through their own means (civilizational [sic] uplift is not an option, I suppose). It's survival of the fittest as decreed by the Federation, and those who cannot progress to an advanced developmental stage or who destroy themselves first simply didn't deserve to be in the Federation in the first place.?
