A system, or procedure, for sorting out, or organizing, your thoughts about a case or possible case:


Try one of the following two methods to view and play with MarshalPlan 5.0:

1. MarshalPlan on the web: If you use Firefox 3.x and you are willing to accept a plug-in, you may be able to view MarshalPlan 5.0 in your (Firefox) browser. To try this, click this link

2. This is the simplest method and should work for almost everyone: Go to this folder and download the version of the software that works with your operating system (i.e., Windows, Linux, or some Apple operating system).
  • The main disadvantage of this method of downloading MarshalPlan is that some of the otherwise spoken explanations and notes appear only as text. But this is not a significant disadvantage -- unless you hunger for the sound of the (virtual) human voice.

    Caveats about MarshalPlan 5.0:

    1. The current iteration of MarshalPlan -- MarshalPlan 5.0 -- is not a prototype of a working application suitable for real-time and real-world use. Far from it! However, MarshalPlan 5.0 goes beyond scratchings (text) that state how an evidence marshaling application might work. But it is not far from the truth to say that MarshalPlan is mainly an elaborate visual illustration of some of the directions that development of software for marshaling evidence in legal settings should take. But, but ... MarshalPlan 5.0 is a bit more than an illustration of possible future directions for research and development. MarshalPlan, as it now stands, is useful for pedagogical (i.e., teaching) purposes. Moreover, MarshalPlan is creeping ever closer to being something akin to a genuine software prototype suitable for real-world and real-time use. 
    2. In MarshalPlan 5.0 there are only brief explanations of some of the evidence marshaling strategies found there. Other marshaling strategies, however, are described and explained more fully. For a comprehensive account of the thinking that went into MarshalPlan, please see the readings mentioned above. If you want a truly comprehensive theory-laden explanation of MarshalPlan, you will have to invite me to give a leisurely talk (preferably on a tropical island or some other attractive venue).
    3. A few buttons and links may not work. If that happens, try other buttons and links. (Otherwise resort to expletives. You have my permission.) 
    4. MarshalPlan 5.0 is not set up to be linked to a database. This is a most serious deficiency for any possible real-world use in a context such as law practice.

    General Interests

    In recent decades there have been significant advances in the understanding of evidence and inference. One of my major interests is in making use of some of these advances to gain insights into evidence, inference, and proof in litigation. I have found it particularly useful to ponder Bayesianism, L.J. Cohen's theory of induction and proof, Glenn Shafer's theory of evidence and his theory of causality, inference networks, David Schum's theory of hierarchical inference, and the evolving views and ambitions of AI theorists. My general "take" on the nature of evidence and inference has been heavily influenced by my understanding of Kant's epistemology and its problems. I believe that Hegel (while making a hash of many things) and neo-Kantians such as Ernst Cassirer appropriately recognized that Kantian premises generate more contingency and subjectivity in human knowledge than Kant himself was willing to acknowledge.



    Written ca. 1998:

    A Philosophical Chestnut in Inferential Garb

    There is a longstanding philosophical debate about the relationship between "facts" and "values." This philosophical chestnut takes a particularly interesting form in the context of evidence and inference. Some theorists insist on a sharp distinction between descriptive theories of inference and prescriptive or normative theories of inference. This distinction, however, may be difficult to sustain if one thinks that whenever one describes a form of inference one describes a form of reasoning or logic. Furthermore, close study of inferential argument suggests that the source of many of the principles or generalizations on which people rely when they draw inferences is as likely to be culture as it is to be personal or scientific experience. Students of probability, induction, and inference must in the future think more carefully than they have in the past about the relationship between "rational inference" and matters such as culture and "values." While I am no great fan of movements such as deconstruction, there may be more than is generally acknowledged to the Hegelian idea than that human societies and communities are grand experiments, tests, or wagers of the viability or validity of particular "world views," views of the world that may prove to be right (or wrong) but whose accuracy or adequacy cannot be demonstrated while they are being tested. I hope to examine this matter -- the relationship between "rational inference" and matters such as culture, cultural values, prejudice, personal values, and personal beliefs -- in more detail in the years to come.
