The Logic of Being Misinformed

Sunday, May 23rd, 2010

Have just uploaded a draft of a paper I am working on, titled ‘The Logic of Being Misinformed’, which can be downloaded here. Feedback welcome. Following is the abstract:

It is well established that the states of knowledge and belief have been captured using systems of modal logic. Referred to respectively as epistemic and doxastic modal logics, they have been studied extensively in the literature. In a relatively recent paper entitled ‘The Logic Of Being Informed’, Luciano Floridi does the same for the state of being informed, giving a logic of being informed also based on modal logic. In this information logic (IL), the statement Iap stands for ‘a is informed that p‘ or ‘a holds the information that p‘. After a review of Floridi’s logic of being informed, including an explication of the central concept of semantic information, I go on to develop a complementary logic of being misinformed, which formally captures the relation `a is misinformed that p‘.

Information, Knowledge and Belief

Just came across, somewhat surprisingly, this paper: Information, Knowledge and Belief. It investigates the relationship between information, knowledge and belief via modal logic. What’s more, it was written all the way back in 2000.

A Question Concerning Data

Friday, May 14th, 2010

The rejection of dataless information in accordance with the General Definition of Information leads to the following modest thesis of ontological neutrality:


There can be no information without data representation.

This thesis can be, and often is, interpreted materialistically, with the equation of representation and physical implementation leading to the following:


There can be no data representation without physical implementation.

which leads to


There can be no information without physical implementation.

This is the view of Landauer. A related discussion of the matter can be found here.

Epistemology and the Value of Knowledge

Wednesday, May 12th, 2010

The Value of Knowledge and the Pursuit of Survival, a paper I have just looked at which impressively supports the view that knowledge is more valuable than mere true belief, a view which I support.

A copy of the draft from the author’s website can be found here.

Being a proponent of informational epistemology, one of the things that interests me is how informational accounts of knowledge and general informational notions applied to epistemology can address the Value Problem in epistemology.

Dissecting the General Definition of Information (GDI)

Friday, May 7th, 2010

According to the General Definition of Information (GDI), X is an instance of information, understood as semantic content if and only if (1) X consists of n data, for n >= 1 (2) the data are well-formed (3) the well-formed data are meaningful. So information is made of data, whose nature is itself an interesting topic. ‘Well-formed’ here means that the data are composed according to the rules (syntax) governing the chosen system in question and ‘meaningful’ means that the well-formed data comply with the meanings (semantics) of the chosen system. All this seems straightforward enough, though it does raise some questions.
