Cleanliness is important!

Thanks to Marie. I'm gonna take a liiiiiittle bit different of a tact to approach this resolution. While she, maybe rightfully, focuses on the word "cleanliness" in her case, I see a different word to focus on: important. What does it even mean? What does it mean for something to be "important" as opposed to being unimportant?Merriam-Webster(1) defines important as something "marked by or indicative of significant worth or consequence". This is really crucial to understanding the resolution because we could sit here bantering back and forth all day about the health implications about washing one's walls (I'd fall asleep in minutes from boredom, but we could do it!), but if we don't address why it's important, we're not actually talking about the resolution. But what does it mean for something to have worth? How is something prescribed as "worthy" and under what circumstances can something be prescribed as such?(this was my fancy way of shifting the topic to philosophy, if you couldn't keep up :P)Mark Mercer describes it as what's within our own self-interest. He makes the claim that our decisions, i.e. what we put value and worth into, are decided by what we would prefer rather than some objective metric. He writes(2): "A little more elaborately,weak psychological egoism is the doctrine that behind any action whatever that an agent performs intentionally, ultimately there lies the agent’s expectation of realizing one or more of her self-regarding ends, an expectation without which the agent would not have performed the action. If weak psychological egoism is true, no one ever performs an action intentionally except that they expect to become happy or to forestall unhappiness, or to maintain their self-respect, or to get others to see them in a certain light, or to realize some other self-regarding end, in or through performing it; if an agent does not expect to forestall his own unhappiness or to promote his self-image, or whatever, in or through performing an action of some type, then that agent will not intentionally perform an action of that type." We can see this exemplified in every day behavior. I eat ice cream as a snack over the grass in my front lawn not because the ice cream provides me with some kind of better sustenence or that some all-mighty ruler has declared ice cream to be the ultimate snacking substance, but rather I ultimately would rather have, that is to say it's within my own self-interest to have, ice cream as a snack than grass. Similarly, I drive my car the four or five miles to work that I drive not because car driving is an objectively better mode of transit (avid environmentalists would have you believe that it's the cause of all of the earth's problems), but I would prefer to not walk half an hour to go to work when I can drive there in five minutes. This means we can restructure the resolution a little bit without affecting the meaning too much. "Cleanliness is important" can thusly be read as "Cleanliness is within my own self-interest". This means that all I have to do is show that cleanliness can be outside of my self-interest, and the resolution becomes negated.This puts my opponent in a bit of a predicament here, mainly because this debate's existence is a very solid reason of why cleanliness isn't in my self-interest. The mere fact that I'm disagreeing with my opponent on the importance of cleanliness shows how little I value it currently. In the seventeen years I've lived in my home, I've never once had a problem of "mold" or "grease" on my walls getting me sick, so it's certainly not within my self-interest to care about such things. Moreover, I've never had a problem with pests or rodents coming into my room, therefore it's not within my self-interest to care. I've never had a fire hazard in my room nor are people injuring themselves over anything on my floor, so it's not within my self-interest to care. Moreover, the only person who comes into my room is usually me, therefore making it appear presentable to the non-existent visitors to it is pointless, therefore not in my self-interest. As such the debate becomes something of a truism. I've listed why it's not within my self-interest to care about any of the things my opponent listed as reasons to care about cleaning your room, and the mere fact that this disagreement exists shows that cleaning my room isn't in my self-interest. As such, it's not important to me, therefore negating the resolution. Have fun Marie! ^_^Sources: (1) - http://www.merriam-webster.com...(2) - MARK MERCER. IN DEFENCE OF WEAK PSYCHOLOGICAL EGOISM.
