Humans inflict untold suffering and death on many billions of animals every year, and the overwhelming majority of humans are heavily complicit. - David Benatar

Moreover, it is thought that there is something absurd about the earnestness of our pursuits. We take ourselves very seriously, but when we step back, we wonder what it is all about. The step back need not be all the way to the cosmos. One does not need much distance to see that there seems something futile about our endless strivings, which are not altogether different from a hamster on its wheel. Much of our lives are filled with recurring mundane activities, the purpose of which is to keep the whole cycle going: working, shopping, cooking, feeding, abluting, sleeping, laundering, dishwashing, bill-paying, and various engagements with ever-expanding bureaucracies. Even if these mundane activities are thought to serve other goals, the attainment of those goals only yields further goals to be pursued. There is plenty of scope for questioning the significance of even the broader goals of one’s life. This (personal) cycle continues until one dies, but the treadmill is intergenerational because people tend to reproduce, thereby creating new mill-treaders. This has continued for generations and will continue until humanity eventually goes the way of all species—extinction. It seems like a long, repetitive journey to nowhere.

The argument that coming into existence is always a harm can be summarized as follows: Both good and bad things happen only to those who exist. However, there is a crucial asymmetry between the good and the bad things. The absence of bad things, such as pain, is good even if there is nobody to enjoy that good, whereas the absence of good things, such as pleasure, is bad only if there is somebody who is deprived of these good things.

Although there are many non-human species — especially — that also cause a lot of suffering, humans have the unfortunate distinction of being the most destructive and harmful species on earth. The amount of suffering in the world could be radically reduced if there were no more humans. Even if the misanthropic argument is not taken to this extreme, it can be used to defend at least a radical reduction of the human population.
