We hope you will find these thoughts of ours both interesting and useful." These are words spoken to express an intention, a bearing in the mind of a person toward an object which is yet to be achieved. The readiest moment of human life involves the interplay of signs, ideas, and objects-more explicitly, the interrelation of signifying expressions, states and dispositions of the mind or person, and objects or objectives either actual or potential. Our work designing instruments to enhance the play of inquiry has attuned us to the themes of interpretation and intentionality which every inquiry seems to involve. We hear what sounds like familiar strains reaching us from the hermeneutic quarter. The purpose of this essay is to trace to their sources a few of these potentially common themes, to draw out one line of their historical development, and to gather what consequences they inspire for educational practice and continued inquiry.

Today’s society looks to universities for solutions to broad-based issues that require cross-disciplinary expertise. Yet, the organizational structure of our institutions remains locked in academic and administrative silos that have little genuine ability to communicate or to recognize the interdependence of knowledge. Why does the capacity to communicate between disciplines and units remain limited? How do formalizations of our experience create barriers? What kind of reflection would it take to subject our mental models of knowledge and learning to critical inquiry? This discussion highlights one of the most entrenched ‘group identity myths’ that underlie the structure of modern academic institutions, the ‘triviality of integration’ thesis.

More and more we hear the complaint that the gap between research and instruction is widening and a vital sense of motivation is falling between the cracks. It is our vision that intelligent computing systems will become a partner in the reintegration of discovery and learning within the inquiry process. We will address certain issues that must be faced if computer media are to have the characteristics necessary to support this integration. The development of the computer to date has required a careful attention to the syntax and semantics of the rather limited symbol systems we have induced them to use. A capacity for communicating in multiple modalities with non-uniform communities of symbol users — for sharing in the discovery of a pluralistic universe — will demand a quantum leap in our understanding of the pragmatic dimensions of symbol use. In the future the capacity for inquiry must permeate the living architecture of the computer system. A computer program that begins to embody these ideas will be discussed.

If computer programs were smarter, they would, like people, recognize sequences of events, form models of their environment, and formulate rules based on experience.  This paper describes the development of a program designed to address the difficult computational problems involved in integrating the inductive and deductive reasoning necessary to perform such tasks.  “Theme One” is a prototype program composed of “Index”, a learning algorithm for sequential data, and “Study”, an algorithm for building logical models.  The project goal is an interactive research tool that assists students and investigators in the exploration of qualitative data using artificial intelligence.

Today, society is everywhere pressing for answers to the large, human problems it faces, such as poverty, hunger, and a sustainable environment. As part of this quest for solutions the university has come under scrutiny and duress to apply its knowledge more directly to the needs of the world it inhabits. Mary Walshok (1995) writes of the importance of “knowledge without boundaries”. Donald Schön (1994) and Nicholas Maxwell (1984) implore us to focus on solutions to the large “civilizing problems” of life — to develop the wisdom that will lead to a “better and wiser world” (Maxwell, 1984, 3). Achieving such wisdom will call for an understanding of the interrelationships of knowledge that will allow problems to be reframed and solutions to coalesce in new ways. Beyond translating discoveries into action in the service of society, the university is also being asked to prepare the next generation of citizens with the skills and abilities that are needed to face the challenges of the new world in which they will live — skills such as the ability to construct meaning from knowledge, to recognize connections and interrelationships, to reach beyond what is known through experimentation and inquiry, and to achieve mutual goals through collaboration (Reich, 1991).

Research Interests:
Theme One is a computer program with a dual objective — to perform tasks of inductive and deductive problem-solving that arise in research and to explore the integration of these reasoning types in human and computer information processing.

This report discusses C.S. Peirce's treatment of analogy, placing it in relation to his overall theory of inquiry. We begin by introducing three basic types of reasoning Peirce adopted from classical logic. In Peirce's analysis both inquiry and analogy are complex programs of logical inference which develop through stages of these three types, although normally in different orders. Note on notation. The discussion to follow uses logical conjunctions, expressed in the form of concatenated tuples and minimal negation operations, expressed in the form of bracketed tuples as the principal expression-forming operations of a calculus for boolean-valued functions, that is, for propositions. The expressions of this calculus parse into data structures whose underlying graphs are called cacti by graph theorists. Hence the name cactus language for this dialect of propositional calculus.
