I'm a mere beginner to philosophy and here, I'm not asking about philosophy or any abstraction about, but rather just the logic or strength of the argument for this essay topic: 'Does it matter if some animal and plant species die out?'
Let us approach this question by asking, first, the more dramatic question: Does it matter if all animal and plant species die out? In other words, would the end of the world be important? You might think that, if anything is important, the end of the world is important. But that is not so obvious.
Some philosophers raise the question of whether death matters. The challenge is to show how death can matter to the person who is dead. After all, she is not around to miss her life. It is no answer to say that she has to go through the process of dying first, which can be painful or scary. That only shows that the process of dying can matter to the person going through it. If death is sudden, there is no process of dying. Without the process, how can death matter to the dead person?
It may not matter to the dead person, but doesn't it still matter to those left behind? Usually it does. But this is where we arrive at the challenge of explaining why the end of the world matters. Suppose we all die together and instantaneously. Then nobody is left behind. This seems to prove that the death of all people matters less than the death of one, some, or most people. If we are going to die instantaneously, it is better if we all do, because then there is nobody and nothing left behind to experience the loss and its other nasty consequences. (Think of all the Mad-Max-style 'survivor' stories premissed on how much worse it is to be one of those left behind.)
The bolded seems a fatuous, vague, weak, and ineffective step in the argument. One could argue that 'death' is unknown to all living and thus refute this point. Even with 'the process', death may be hell which does 'matter to the dead person.' Or did I misinterpret the argumentation?
