Logically speaking, an assumption is a supposition, the product of the verb—to assume—which can mean to take upon oneself; to presuppose; to take for granted; to pretend to have/be; or the archaic definition: to adopt.
Religiously speaking, assumption is the bodily progression from earth to heaven, especially with respect to the Catholic faith. For example, the “Assumption of Mary” was the undisputed account of her being taken up to heaven. The “Assumption of Moses,” however, remains controversial. Those who believed in assumption were called “Assumptionists” (a.k.a. Augustinians, named after St. Augustine) and they established twenty or so colleges around the globe, such as Assumption College in Worcester, Mass. http://www.newadvent.org/cathen/02104a.htm
Assumption is also the name of towns in Ohio and Illinois, as well as an island in the Seychelles (Indian Ocean), a parish in Louisiana and a river in Quebec, Canada.
In a game like CLUE, or a modern spin on it, Crime Scene Investigation (CSI) the board game, players make assumptions based on a natural process of deducing a certain set of facts and forming a guess about the crime. In real life, a detective makes assumptions that might be proven correct or false, leading to other conclusions.
Because an assumption can be proven false, there is the old adage: “When you assume, you make an ass of you and me.” This joke might be funny in a variety of “assumption” contexts: mathematical modeling, real property law (transferring the mortgage from seller to buyer), or reinsurance of policy claims. But perhaps the most unusual type of “assumption” is a fictional Poker game played with Tarot cards, as featured in the novel Last Call by Tim Powers. The stakes are high as they come with a spiritual twist on the usual pot. Players should be wary of this water caveat: “Assumption must never be played over “untamed” water like a natural lake, river, or ocean. Man-made bodies of water like Lake Mead are useful sites for play, and in fact the climactic final game takes place over that lake.” http://www.sff.net/people/lucy-snyder/brain/2005/12/playing-poker-with-tarot-cards.html
Strangely enough, that poker game is not nearly as complex to stake-holders as state assumption of the Section 404 program under the Clean Water Act is for states. In this context, assumption is the states’ option to apply to adopt the regulatory authority for the 404 program, which regulates dredge and fill activities in streams and wetlands. Currently there are only two states, Michigan and New Jersey, which have assumed the 404 program. Other states have shown great interest and yet, few people outside of state wetland programs have heard of assumption. I know a little about it because I had to become an expert on the subject after two years of research. I developed fact sheets on assumption for the U.S. Environmental Protection Agency and the Army Corps of Engineers. Everything I learned about it is posted on this webpage I put together for ASWM here.
ASWM and the Environmental Council to the States, as well as EPA and a number of states have been working to clarify the application process for states to assume §404. The group is drafting a handbook, which will offer much needed guidelines to states.http://aswm.org/wetland-programs/s-404-assumption
And by the way, if Strange Wetlands ever takes on a swamp rock cover band, they’ll be called the Assumptionists.
Summary of the June 22, 2009 Supreme Court Decision in Couer Alaska, Inc. v. Southeast Alaska Conservation Council, et al. In 6-3 Clean Water Act ruling that could allow lakes and other waters to be more easily destroyed and polluted by mining and other polluting activities, the Supreme Court today upheld that an unprecedented agency permitting decision allowing the Couer Alaska mine company to avoid stringent permitting requirements and instead dump their waste directly into Alaska’s Lower Slate Lake.
