Does Panpsychism Mean That 'We Are All One'?

Panpsychism is the view that all things are associated with consciousness. Panpsychism has a number of significant theoretical implications, with respect to the mind–body problem and other problems in metaphysics. Here I will consider one of its potential practical or ethical implications; specifically, whether, if panpsychism is true, it follows that 'we are all one', in a sense that implies that egoism (understood as bias towards what we normally take to constitute the self or ego) is not only immoral but fundamentally irrational (or imprudent).
