JA: Peirce continues a classical line of calling logic a normative science,
    a science of how we ought to do things if we want to achieve a certain
    class of objectives.  This makes logic, whose object is truth, akin to
    aesthetics, whose object is beauty, pleasure, or experiential goodness,
    and ethics, whose object is virtue, justice, or comportmental goodness.

JA: What is the good of logic?  The classical answer is "truth".

JA: What is truth?  It's a property of a sign, or a representation,
    that makes it a good sign, a representation that is so natured
    or so designed as to further the achievement its proper object.

JU replied:

JU: In a recent discussion on spatio-temporal representations of 'apparently'
    straightforward realworld concepts such as the difference between a river
    and a lake in GIS, the environmentalists, the geographers, the fishermen,
    the freshwater biologists used very different criteria reflecting fact
    that the 'proper object' they sought to achieve were not the same.

You'll undoubtedly find me quoting Chapter & Peirce later on,
but I made an effort to say things in my own words this time,
hence the fuzziness at certain points.  But I would not have
meant to suggest any sort absolute, short-term uniqueness by
employing the phrase "proper object", since it goes with the
territory of pragmatic thinking that objects are relative to
context and purpose.

JU: However…the Ordnance Survey team will make a choice.
    We will then all adopt and use it as a given when the
    maps come out.  It will then become so embedded in a
    range of other processes that will make it well nigh
    impossible to coordinate activities without reinforcing
    it as a benchmark.

I like this talk of maps and how they figure in coordinating activities.

JU: Like the aboriginal songlines we do appear to create and recreate many
    aspects of the ‘real’ world by validating and enacting those we agree on.

The concept of a "manifold", defined over an "atlas" of "charts", is one
of the ways to formalize the task of constructing a consensual picture of
an objective reality.

JU: Peirce said that:  The opinion which is fated to be ultimately agreed to by
    all who investigate, is what we mean by the truth, and the object represented
    in this opinion is the real.  Perhaps over-egging the pudding a little but think
    there is something to it!

You can't make a pragmatic frittata without a bit of over-egging ...
