I can imagine someone objecting to me as follows:
Why the careful and respectful attention to the anti-natalist writings of David Benatar and others when the West, Europe especially, is under dire existential threat from hordes of non-Western immigrants who have no intention of assimilating but aim at cultural conquest? Anti-natalism is an expression of exhaustion and decadence. By taking it seriously, you lend it credibility and aid and abet the decline of the West!
To answer directly: the aim of the philosopher is truth, whatever it is, whether it serves his form of life or not, whether it serves any form of life or not.
