Explorationism (see www.bu.edu/wcp/Papers/Logi/LogiFaus.htm, WCP XX, “Conflict without Contradiction”) is a perspective concerning human knowledge: as yet, our ignorance of the Real World remains great. With this perspective, all our knowledge is so far only partial and tentative. Evidence Logic (EL) (see “The Concept of Evidence”, INTER. JOURNAL OF INTELLIGENT SYSTEMS 15 (2000), 477‐493) provides an example of a reasonable Base Logic for Explorationism:EL provides machinery for the representation and processing of gradational evidential predications. Syntactically, for any evidence level e, for (...) a proposition symbol P, Pc:e asserts that there is level e confirmatory evidence regarding P, while Pr:e asserts level e refutatory evidence (n‐ary predications, for n>0, are handled similarly). Semantically, EL has similarly enriched model spaces. The Boolean sentence algebras of the variety of EL languages, varying across stipulated families of predicate and functions symbols, have been analyzed, and EL is sound and complete. Belief Systems, we will argue, are all unnecessary: in science, as well as in all broader domains of human relations and activity, it is always sufficient to have simply commitments, which entail no assertion of Truth but rather simply entail agreed‐upon consequent actions. (Agent A believes a sentence S if A asserts S is True although A does not know (have absolute evidence) that S is True.) We will further seek to explore ways in which such a perspective may help in engendering more enhanced discourse, less absolutist and shrill advocacy and violence, and more rationality, in the Global Village of the new century.

Collaboration must be based on careful representation and communication of each stakeholder’s knowledge. Using a foundational logical and epistemological point of view, we explore how such representation and communication can be accomplished. We tentatively conclude, based on careful delineation of logical technicalities necessarily involved in such representation and communication, that currently a complete representation is not possible. This inference, if correct, is discouraging. However, we suggest two actions. First, we can strive to make stakeholders more aware of the incompleteness of (...) knowledge representations. Second, moderating one’s certainty of “Truth” should increase each stakeholder’s humility, thereby promoting the efficacy of collaborations. (shrink)

Using Evidence Logic (EL), a logic which is conceptually to Classical Logic and which is equipped with both gradational confirmatory predications and gradational refutatory predications, further investigation of some of the persistent problematic aspects of negation is facilitated. This perspective helps to illuminate distinction of “absence of evidence”, and may help further understanding of the semantics of negation.
