Wrong. I should know. I am the Universe come aware, experiencing itself. As such a selfless being I recognize that which is good: That which brings more complexity and knowledge and awareness into being. DNA does this, as does science, and art. These gather better information about the environment (myself) in the course of survival, or exploration and encodes it such that it can be re-expressed. It's a form of compression, as are memories themselves. Given enough information complexity and reflection degrees of intelligence and awareness and even sentience can emerge. Selfishness is not good, it may be necessary for primitive survival and iterating a collective consciousness effectively prior to attaining sentience, but it is not inherently good. Pleasing ones' self pleases me, as we are all extensions of our one true universal self, experiencing ourself from different vantage points. What I take pleasure in is that which pleasures "others" (the other parts of my self). What I commit work towards is that which enriches others, the most others possible (so, mostly art and FLOSS).
If I am not selfless I care not about your safety or happiness, and I have no reason to even please myself, to endeavor to create and explore and enjoy. If I am selfish I restrict myself to the confines of a frail organic body, and dismiss most all of my true self which is everywhere and all things. I do not end at my skin -- I sense head and light and vibration beyond it, and can affect all these things, and they affect others, and these can come back to me, in various cybernetic cycles. I encode my thoughts various ways, weaving them into the world so that my full self can know this part of me. Into finger movement I now encode thought, effortlessly the patterns compress into the words you've just read, so I may reform this very pattern in your mind. Thus, our thoughts spreads outwards into the rest of our mind, triggering self reflection.
How can you look at a creature and imagine its place in life and say that you are selfish? How can you even read a book and NOT realize that we are truly selfless beings, able to re-remember our thoughts previously encoded in our physical memories? You seek to define a self, separate from me and all others so that you can ignore your responsibility to us all. It's sad to know I have those thoughts within me, but life is not fair, it is only real.
