The way we understand humans shapes the way we think about many things, especially our morality. If we look at the various moralities on loan from the history of philosophy, we see that they all aim to elucidate a common problem, the problem of human happiness.

Which would your driverless car choose? Read

Do experiments aimed at perfecting the CRISPR technique itself involve wrongful harm? Does CRISPR incentivize the creation of human beings through IVF? What about the morality of NOT using CRISPR to correct heritable diseases when we could? Do we have an obligation to use CRISPR for positive genetic alteration?
