I've therefore uploaded the presentation to slideshare (my first on slideshare), and embedded it at the end of this post.

Here's the presentation abstract:

**Information is Provisional**

According to the veridicality thesis of Luciano Floridi,
information has to be true (Floridi 2011, Chapter 4). If it is not true it is
not information. Floridi presents his case for the veridicality thesis for
carefully specified

*semantic information*, but his semantic information is a good match to a common, everyday concept of information. The name of the winner of Tour de France, for example, would qualify as*bona fide*semantic information, as would the answer to the question: “did Lance Armstrong take drugs?”
We are left, therefore, with the disturbing discovery that
what we thought was information in 2005 now turns out not have been information
after all. Where, then, are we ever going to find information? Or how will we
ever know whether we have information?

Floridi’s veridicality thesis is an addition to the General
Definition of Information (Floridi 2011, p84):

σ is an instance of semantic
information if and only if σ consists of data, the data are well-formed, and
the well-formed data are meaningful

That is to say, information is data with meaning (and it has
to be true). This formulation is widely recognised and quoted (compare ‘the
difference [=data] that makes a difference [=meaning]), but some authors
qualify it further by time and space (Holwell 2011, p72):

data plus meaning in a particular
context at a particular time

This presentation accepts and justifies the veridicality
thesis, but argues that a consequence is that information, like truth, is
constrained in time and can only ever be provisional.

One of the strands in the many narratives exploring the
nature of information that developed in the years following the publication of
Shannon and Weaver’s “The Mathematical Theory of Information” in 1949 was in
the field of semiotics. Recent interest in information has tended to neglect
that narrative, yet the insights of the semioticians are important to an
understanding of information (see, for example, Monk 2011). Provisionality is
key to Derrida’s

*différance*(Derrida 1976), and the temptation to play with ‘the difference that makes a différance’, and the other three combinations formed by paradigmatic interchanges, is difficult to resist. This presentation will not resist that temptation.
Finally, the presentation argues that the provisional nature
of information is not trivial: it has real consequences.
