Fear of death can both spur people on to action and cause laziness. On one hand, it’s possible that fear of death would cause a person to take action to keep death at a distance, to do things which make their life better and longer. On the other hand, a person may see the world as a threatening place and be adverse to taking any risks, be paralyzed by fear, and not take action at all, using a retreat into inaction as a way to deal with this fear. Thus, they can fall into a habit of fearful laziness.
I’d like to say something on fear of death for a moment. I think that fear of death is the biggest cause of failure, destruction, and general dysfunctionality for humanity. Humans were not initially equipped to deal with fear of death, and one of the only mechanisms they were able to develop over time was outright denial of death. This gave rise to cults of immortality which use relieving peoples’ fear of death as a way to ensnare, manipulate, and exploit their members. Toxic cultures rise because of fear of death, and they fall because of it too. Fear of death is mostly responsible for the laziness of humanity, and while I stated that fear of death can spur people on to action, most react to it by becoming lazy.
The suffering of life reminds people that they’re fallible, that they are not immune to the laws of nature and that life takes from them, and that it could even take their life. In addition to the suffering of life, the reminder of fear of death adds on more suffering, and so laziness happens as a response. In many ways, laziness is a retreat back into the womb, where no suffering is demanded of the person.
But suffering is demanded of people; as stated many times on this site, anything that one needs or wants in life requires someone to suffer, and so the person who retreats into laziness cannot remain in this false womb unless someone suffers in their place. People very often do make other people suffer in their place, however, as can be seen by the phenomenon of capitalism where each higher class in society feeds off of those beneath them.
Those who live in bourgeois and upper class comfort are also living in a womb which shields them from thinking about the reality of their own deaths, and they cause many people to suffer much more than necessary in order to maintain this state of affairs. Life demands suffering of everyone, but the upper classes benefit from the suffering of the lower-classes and give them very little gain for it. If the working class were to not only demand a just benefit for their suffering, but also take it, they would be able to live life and know the true fruits of their labor, which would allow a closer engagement with reality, and reduce the alienation of civilized life.
