Paley’s Watch is Broken
A person walking along a beach stumbles upon a watch lying in the sand. Without even knowing what it is this person recognizes that this object is complex and has a purpose and so this person will determine that the watch didn’t spring up by itself it must have a creator. Similarly the universe (or life on this planet) is complex and demonstrates purpose so must have a designer.
That’s a variation of the Watchmaker Analogy, or the Watchmaker Fallacy depending on which side of the divide you’re on. In 1802 a Christian apologist named William Paley published a book called “Natural Theology” where he laid out his case for the existence of God as the only rational explanation for the existence of life on this planet. The Watchmaker Analogy is Paley’s most famous contribution to apologetics and has survived more than two hundred and ten years despite the fact that it is quite simply riddled with flaws and assumptions.
The idea that someone can determine whether something was designed by a designer simply by observing it is an outright assumption with no factual basis. In reality we recognize a watch as being designed because we are intimately familiar with watches. We know that they don’t occur naturally, we’re familiar with machinery and with the concept of metalwork. Also we know for certain that watchmakers exist. They are an actual verifiable group of people who can be definitively shown to produce watches. The same cannot be said of any universe creator.
We recognize design by its superficial complexity. By that I mean the obvious “unnatural” order that stamps our creations. For instance when you compare an office building to a mountain the artifice, the engineering, in short the design of the building is immediately apparent. This brings up another flaw of Paley’s argument. We recognize design by comparing it to naturally occurring phenomena. According to Paley’s own argument the very complexity of the watch points to its having been designed but one has to ask: complexity when compared to what? The rocks? The trees? The sky? The watchmaker analogy is attempting to show that all things are designed by comparing the apparent complexity of human creation to the apparent simplicity of natural phenomena. It undercuts its own central thesis.
The Watchmaker Analogy states that complexity requires design and by expansion it declares the obvious truth that design requires a designer. Yet it ignores the simple fact that any designer with the power and ability to design all life on earth (let alone the entire cosmos) must be a being of surpassing complexity in and of itself. By the logic of the analogy the creator itself would require a creator of its own, as would that creator and so on infinitely.
The analogy is often used to attempt to hold up a specific theology (Christianity, Islam, etc) yet it doesn’t actually make any attempt to define who or what the designer may be. Even if you accept the Watchmaker in its entirety it doesn’t get you any closer to proving any particular theology. It can, at best, get you to deism. On it’s own Paley’s analogy is insufficient to draw any conclusions whatsoever about the designer. Within the bounds of the analogy there is actually no reason to assume it’s a single designer rather than a series of cooperating entities (for example). The Watchmaker supports equally the idea that reality was formed by an army of magical pixies as it does the idea of any all-powerful monotheistic god.
This analogy has survived as long as it has because it is a clear and concise phrasing of what seems, on its face, like a reasonable supposition. It survived unmolested for almost sixty years until it was completely destroyed by, ironically, a student of Paley’s works named Charles Darwin. Darwin’s evolution by natural selection showed us (well most of us) that complexity does not in fact require design. It showed us that complexity can and in fact does result from gradual adaptation and mutation over long periods of time. It demonstrated that deity is not necessary and provided an actual answer without the endless regression that the god hypothesis always results in. Despite the efforts of generations of apologists, theists and religious “scientists” natural selection remains the best answer we have ever developed for the “how” of existence while The Watchmaker analogy has become a sound bite for those too invested in their preconceptions to take an honest look at the realities around them
