Can oneself be ever satisfied? The answer is quite obvious. If we are finite beings, it follows we will never be totally satisfied. Or is that not right? For one could also say that because we are finite, then that is why, on the contrary, we can be completely fulfiled. But it seems common sense saying we are insatiable—by our very nature. The question cannot be either of those mentioned above. Now we must ask ourselves: how can these two accounts be possible? How can one person say we are completely insatiable because of our finitude, when another says we can actually be satisfied because of the same reason, that is, we being finite?
All things are always changing. If we needed permanence in order to fulfil our desires then we would inexorably be unhappy and dissatisfied. Yet, if we cannot afford stoping things from change, at the same time there is something permanent going on here—change being unavoidable, it is also permanent. In this case, perhaps, the person who absolutely needs permanence could have it with eternal variance. And the other who does want change, may be happy with a continuous sort of it.
But why is it so easy thinking that no-one can be really happy in this world? Aristotle said, in the beggining of his Nicomachean Ethics, that men are born to be happy and to seek happiness (or eudaimonia in ancient Greek). If men are born needing to look for happiness, it is not hard to conclude that we are born unhappy and aspiring to something we do not have. Satisfaction of our desires and needs is the first object of human will. There is a hole we feel and have to fill. We are beings of wanting, since we are incomplete.
However, who is capable of assuring we are incomplete? Unfortunately, that is not a good objection. Everything we are in need of, we do not have. And a being that is not self-sufficient is not an indepedent one; and so depends on, at least, other people—if we are to ignore higher needs, which arise inevitably due to our short breath on this Earth. Death is another limit human beings have to face. We ourselves are scarce, we ourselves do not have that many resources. And so expiration is inevitable, as breathing once was.
Our question is still posed. And there are two philosophical claims that correspond to each of them. The first one is of an atheist kind; it is the defense of a good life (or beatitude in Spinoza’s terminology) here in this world. The other acknowledges this life as one of misery, although some sort of happiness is to be found through Grace, that is, if God so wishes. In this case, evil is inevitable and the only remedy humans may found is Hope.
All of which is a new question already.
