Solving the pink and invisible problem
Normally most people that know of the Invisible Pink Unicorn (henceforth, IPU) believe that it cannot logically exist, because pink and invisible are inconsistent, but I think that I found a solution.
The problem lies in the definition of ‘invisible’. Normally, one would probably define it as “that which cannot be seen” and then implying that what cannot be seen emits/reflects no light which contradicts pink meaning “that which emits/reflects light at some particular wave length”.
However, being inspired by a certain Mr. Potters cloak, I discovered another plausible definition of ‘invisible’ which is “that which looks like the environment, so that any observer cannot detect it, as anything other than the environment in which the entity is”. This in conjunction with the essential thesis (discussed below) implies that the IPU can only, logically possible, be in pink environments.
The essential thesis
The essential thesis is a view about what the IPU is. More specifically, what it essentially is. The essential thesis holds that the IPU is essentially invisible, pink, a horseoid and has only one horn. A things essence is the set of properties which the thing cannot lack, for if it did, it would not be the thing we are talking about. The essential thesis has some relevance for the next question.
How is the IPU able to act in a non-pink world?
This deals not with how the IPU does it, but how it is able to do so, without contradicting logic. One plausible theory, called the instant transformation theory claims that the IPU is very keen on changing the environment. If the IPU wants to go a place that is not currently pink, the IPU changes the environment to pink for an infinitesimal amount of time. This allows the IPU to move to the place, do whatever it wants to do (and do so very quickly), and change the environment back into its normal colors.
This theory is being disputed by followers of another theory, called the constant change theory. This theory asserts that the IPU is constantly changing the environment into pink and then back again before anyone notices it. This way, the IPU can almost stay in an area. For instance, it would choose two blocks. Make block (a) pink, move there, make block (b) pink, move there, restore block (a), act, make block (a) pink and move there while restoring block (b) etc.
This is an important discussion within the IPU thinkers circle. Another new theory challenges these two by asserting that the IPU is not essentially pink, but only mostly. This way, it does not have to change the environment at all. Obviously, such a theory has evoked much criticism from followers of the two others theories.
The nature of pinkness
Another very important topic in IPUlogy is the nature of pinkness. It deals primarily with the question of what pink is. Most people believe that pink is property, and most also agree that its a divine property. However, a small fraction of IPUers believe that pink can also be an object which can exist independently of another object. The primary reason for denying this is that it conflicts with the belief that true pinkness is reserved only for the IPU.
I have successfully defended the IPU against attacks from vicious nonbelievers and elaborated on some of the exciting topics in IPUlogy.
