Have meditated further on this matter, two areas of enquiry immediately sprang to mind.
i) Is there any basis for human rights after first contact has been made with an equally or possibly superior intellectual alien species? My thoughts are there can only be three directions

(a) the abandonment of rights for contractarian altruism (call it duty if you like)(do unto others as you’d have done unto yourself),

(b) the development of graded rights with sentient beings at the top followed by ‘lesser’ animals, plants, minor organisms,

(c) the rights emancipation of all organic life systems (almost a Gaia philosophy), celebrating our mutual molecular relationship (Remember you are dust and to dust you shall return).

ii)  What about philosophy for non-organic life forms? I was thinking along the lines of Bladerunner and the writings of Isaac Asimov on Robotics. Surely the more advanced artifically intelligent life forms we seek to develop will have the capacity to take that first step in philosophy and enquire? I defer to your knowledge on this matter but I’m sure that there are already AI systems in development or in existence that are able to process the one word enquiries who, where, what, how, why?

The conclusion that my meditation brought me to was that speculating on alien philosophy is an important development in the field of philosophy, for one thing it can do is lead us to develop a greater understanding of our own philosophical systems. Perhaps as I said in an earlier post, Science Fiction is a branch of philosophy.
