Historically and still today, many people believe that humankind is the creation of a supernatural entity called God, that God had an intelligent purpose in creating humankind, and that this intelligent purpose is the ‘meaning of life’. I do not propose to go through the various arguments for and against the existence of God. However, even if God exists, and even if He had an intelligent purpose in creating humankind, no one really knows what this purpose might be, or that it is especially meaningful. The Second Law of Thermodynamics states that the entropy of a closed system such as the universe increases up to the point at which equilibrium is reached, and God’s purpose in creating humankind and, indeed, all of nature, might have been nothing more lofty that to catalyse this process. If our God-given purpose is to act as super-efficient heat dissipaters, then having no purpose at all is better than having this sort of purpose because it frees us to be the authors of our own purpose or purposes and thereby to lead truly dignified and meaningful lives. For this same reason, having no purpose at all is better than having any kind of purpose, even a more traditional and uplifting purpose such as ‘serving God’ or ‘improving our karma’. In short, even if God exists, and even if He had an intelligent purpose in creating humankind (and why should He have had?), we do not know what this purpose might be and, whatever it might be, we would rather be able to do without it. Unless we can be free to become the authors of our own purpose or purposes, our lives may have, at worse, no purpose at all, and, at best, only some unfathomable and potentially trivial purpose that is not of our choosing.
Some might object that not to have a pre-determined purpose is, really, not have any purpose at all. However, this is to believe (1) that for something to have a purpose, it must necessarily have been created with a purpose in mind, and (2) that something that was created with a purpose in mind must necessarily have the same purpose for which it was created. Last summer, I visited the vineyards of Château-Neuf-du-Pape in the South of France. One evening, I picked up a beautiful rounded stone called a galet which I later took back to England and put to excellent use as a book-end. In the vineyards of Château-Neuf-du-Pape, the declared purpose of these stones is to absorb the heat from the sun during the daytime and then to release it during the night time. Of course, these stones were not created with this or any other purpose in mind. Even if they were created with a purpose in mind, then this purpose was almost certainly not to make great wine, serve as book-ends, or be beautiful. That same evening over supper, I got my friends to blind-taste a bottle of claret that I had brought along from England. As I did not have a decanter to hand, I kept the wine in its bottle and masked the identity of the bottle by slipping it into one of a pair of socks. Unlike the galet, the sock had been created with a purpose in mind, even though this purpose was very different from (although, note, not strictly incompatible with) the one that it eventually found.
In summary, whether or not God exists, and whether or not He has a purpose for us, we should strive to create our own purpose or purposes. In Sartrean terms, whereas for the galet it is true only that existence precedes essence, for the sock it is true both that essence precedes existence (when the sock is used on a foot) and that existence precedes essence (when the sock is used other than on a foot, for example, as a bottle sleeve). Human beings are either like the rock or like the sock, but whichever one they are like, they are better off creating their own purpose or purposes. To re-iterate, unless we can be free to be the authors of our purpose or purposes, our lives may have, at worse, no purpose at all, and, at best, only some unfathomable and potentially trivial purpose that is not of our choosing. Plato once defined man as an animal, biped, featherless, and with broad nails, but another much better definition that he gave was simply this, ‘A being in search of meaning.’
