Towards New Probabilistic Assumptions in Business Intelligence

Issue: 3:4 (The twelfth issue)
One of the main assumptions of mathematical tools in science is represented by the idea of measurability and additivity of reality. For discovering the physical universe additive measures such as mass, force, energy, temperature, etc. are used. Economics and conventional business intelligence try to continue this empiricist tradition and in statistical and econometric tools they appeal only to the measurable aspects of reality. However, a lot of important variables of economic systems cannot be observable and additive in principle. These variables can be called symbolic values or symbolic meanings and studied within symbolic interactionism, the theory developed since George Herbert Mead and Herbert Blumer. In statistical and econometric tools of business intelligence we accept only phenomena with causal connections measured by additive measures. In the paper we show that in the social world we deal with symbolic interactions which can be studied by non-additive labels (symbolic meanings or symbolic values). For accepting the variety of such phenomena we should avoid additivity of basic labels and construct a new probabilistic method in business intelligence based on non-Archimedean probabilities.

The Swarm Computing Approach to Business Intelligence

Issue: 4:3 (The fifteenth issue)
We have proposed to use some features of swarm behaviours in modelling business
processes. Due to these features we deal with a propagation of business processes in all
accessible directions. This propagation is involved into our formalization instead of
communicating sequential processes. As a result, we have constructed a business process
diagram language based on the swarm behavior and an extension of that language in the
form of reflexive management language.

Logics for Physarum Chips

Issue: 5:1 (The seventeenth issue)
The paper considers main features of two groups of logics for biological
devices, called Physarum Chips, based on the plasmodium. Let us recall that
the plasmodium is a single cell with many diploid nuclei. It propagates
networks by growing pseudopodia to connect scattered nutrients (pieces of
food). As a result, we deal with a kind of computing. The first group of logics
for Physarum Chips formalizes the plasmodium behaviour under conditions of
nutrient-poor substrate. This group can be defined as standard storage
modification machines. The second group of logics for Physarum Chips covers
the plasmodium computing under conditions of nutrient-rich substrate. In this
case the plasmodium behaves in a massively parallel manner and propagates in
all possible directions. The logics of the second group are unconventional and
deal with non-well-founded data such as infinite streams.

Preface. Philosophy and History of Talmudic Logic

Issue: 6:2 (The twenty second issue)
The purpose of the workshop Philosophy and History of Talmudic Logic held on October 27, 2016, in Krakow, Poland, was to examine the meaning of Talmudic hermeneutics in the contemporary epistemology and logic. One of the main features of Judaism is that Jewish religious laws are not dogmatic but based on specific legal reasoning. This reasoning was developed by the first Judaic commentators of the Bible (Tann’ayim) for inferring Judaic laws (halakah) from the Pentateuch. Our workshop was aimed to consider Judaic reasoning from the standpoint of modern philosophy: symbolic logic, rhetoric, analytic philosophy, pragmatics and so on. On the one hand, we are interested in possibilities to import into the Talmudic study modern logical methods. On the other hand, we are interested in possibilities to export from the Talmud new logical principles which are innovative to contemporary logic.

On the Babylonian Origin of Symbolic Logic

Issue: 6:2 (The twenty second issue)
The logical reasoning first appeared within the Babylonian legal
tradition established by the Sumerians in the law codes which were first
over the world: Ur-Nammu (ca. 2047 – 2030 B.C.); Lipit-Ishtar (ca. 1900 –
1850 B.C.), and later by their successors, the Akkadians: Hammurabi (1728
– 1686 B.C.). In these codes the casuistic law formulation began first to be
used: “If/when (Akkadian: šumma) this or that occurs, this or that must be
done” allowed the Akkadians to build up a theory of logical connectives:
“... or…”, “… and…”, “if…, then…”, “not…” that must have been applied
in their jurisprudence. So, a trial decision looked like an inference by modus
pones and modus tollens or by other logical rules from (i) some facts and
(ii) an appropriate article in the law code represented by an ever true
implication. The law code was announced by erecting a stele with the code
or by engraving the code on a stone wall. It was considered a set of axioms
announced for all. Then the trial decisions are regarded as claims logically
inferred from the law code on the stones. The only law code of the Greeks
that was excavated is the Code of Gortyn (Crete, the 5th century B.C.). It is
so similar to the Babylonian codes by its law formulations; therefore, we
can suppose that the Greeks developed their codes under a direct influence
of the Semitic legal tradition: the code was represented as the words of the
stele and the court was a logic application from these words. In this way the
Greek logic was established within a Babylonian legal tradition, as well.
Hence, we can conclude that, first, logic appeared in Babylonia and,
second, it appeared within a unique legal tradition where all trial decisions
must have been transparent, obvious, and provable. The symbolic logic
appeared first not in Greece, but in Mesopotamia and this tradition was
grounded in the Sumerian/Akkadian jurisprudence.

translation of Swāmī Abhishiktānanda’s Guru and
Disciple (Moscow, Ganga, 2013). His current academic
interest is in the field of North Indian rural bhakti
movements with a special focus on Nānak-panths as
well as on Rāma-rasika traditions’ poetry and practices.

Reflexive Games in Management

Issue: 7:1 (The twenty fifth issue)
In this paper reflexive games are defined as a way to act beyond equilibria to
control our opponents by our hiding motives. The task of a reflexive game is to
have the opponent’s actions become transparent for us, while our actions remain
obscure for the competitor. In case a reflexive game is carried out between agents
belonging to the same organisation (corporation, company, institute), success in a
reflexive game can be reached by a purposeful modification of some components
of a controlled system. Such a modification for the guaranteed victory in a
reflexive game is called reflexive management. This kind of management uses
reflexive games to control a knowledge structure of agents in a way their actions
unconsciously satisfy the centre’s goals.

Creative Reasoning and Content-Genetic Logic

Issue: 7:4 (The twenty eighth issue)
In decision making quite often we face permanently changeable and potentially infinite databases when we cannot apply conventional algorithms for choosing a solution. A decision process on infinite databases (e.g. on a database containing a contradiction) is called troubleshooting. A decision on these databases is call d creative reasoning. One of the first heuristic semi-logical means for creative decision making were proposed in the theory of inventive problem solving (TIPS) by Genrich Altshuller. In this paper, I show that his approach corresponds to the so-called content-generic logic established by Soviet philosophers as an alternative to mathematical logic. The main assumption of con tent-genetic logic is that we cannot reduce our thinking to a mathematical combination of signs or to a language as such an d our thought is ever cyclic and reflexive so that it contains ever a history.

Logical Determinacy versus Logical Contingency. The Case of Łukasiewicz’s Three-valued Logic

Issue: 8:2 (The thirtieth issue)
In constructing the three-valued logic, Jan Łukasiewicz was highly inspirited
by the Aristotelian idea of logical contingency. Nevertheless, we can construct
a four-valued logic for explicating the Stoic idea of logical determinacy. In this
system, we have the following truth values: 0 (‘possibly false), 1 (‘necessarily
false’), 2 (‘possibly true’), 3 (‘necessarily true’), where the designated truth
value is represented by the two values: 2 and 3.

Judgments and Truth: Essays in Honour of Jan Woleński

Issue: 9:3/4 (the thirty fifth/sixth issue)
It is a Preface to Volume 9:3/4 that has brought a renewed focus to the role of truth conceptions in frameworks of semantics and logic. Jan Woleński is known due to his works on epistemological aspects of logic and his systematization of semantic truth theory. He became the successor and the worthy continuer of prominent Polish logicians: Alfred Tarski and Kazimierz Ajdukiewicz. This volume is collected on the 80th anniversary of Woleński’s birth and draws together new research papers devoted to judgments and truth. These papers take measure of the scope and impact of Woleński's views on truth conceptions, and present new contributions to the field of philosophy and logic.
