This document discusses the history and current state of logic education for philosophers in Japan. It provides background on several important figures who helped establish the logic tradition in Japan, including Ono Katudi, Takeuti Gaishi, Ishimoto Arata, Seki Setsuya, and Maehara Shoji. It then describes the development of logic textbooks in Japan from translations in the late 1980s to original works in the 1990s-2000s. The document also discusses factors like higher education policy changes and economic conditions that impacted logic education. Finally, it summarizes the results of a survey of logic education in U.S. philosophy departments.

28. Logic education for philosophers: a case in Japan ASL questionnaire
ASL guideline 2004
Recommendations for beginning post-secondary education
All post-secondary institutions should offer at least one
introductory course which teaches the basic notions of logic. All
students should be encouraged to take such a course. These
courses should include the following:
The informal notion of ”logically correct argument”.
Informal strategies for producing logically correct arguments and
counterexamples to fallacious arguments.
The propositional calculus as an example of a formal language,
formal proofs, and the formalization of natural language
arguments.

29. Logic education for philosophers: a case in Japan ASL questionnaire
ASL guideline 2004
Recommendations for beginning post-secondary education (cont’d)
All post-secondary institutions should offer at least one
introductory course which teaches the basic notions of logic. All
students should be encouraged to take such a course. These
courses should include the following:
A discussion of the relationship of proof, truth, and
counterexamples, including a discussion of the Soundness
Theorem.
The predicate calculus extension of propositional logic.
At least an informal discussion of the Completeness Theorem, if
time permits.
Yuko Murakami (Tohoku University) December 13, 2012 29 / 69
30. Logic education for philosophers: a case in Japan ASL questionnaire
ASL guideline 2004
Recommendations for advanced post-secondary education
Institutions of higher learning should, in addition, offer a course
or (sequence of courses) which cover the following logic-related
topics.
Elementary facts about sets (up through basic facts about
binary relations, the diagonal method, the proof that
uncountable sets exist, and the basic properties of countable
sets).
Basic facts about inductive definitions and proofs by induction,
of the kind that permeate logic.
Propositional and Predicate Calculus (The formalization of
informal argument, the axiomatic method in mathematics and
science).
Semantics (truth and validity, definability, the Soundness
Theorem, the notion of consistency, the Gdel Completeness
Theorem).
Yuko Murakami (Tohoku University) December 13, 2012 30 / 69
31. Logic education for philosophers: a case in Japan ASL questionnaire
ASL guideline 2004
Recommendations for advanced post-secondary education (cont’d)
The course’s format, the instructor’s field, and the interests of
the students and instructor will all influence the tone, the
presentation, the emphasis, and the choice of additional topics.
The basic concerns and results of logic listed here, however, are
relevant and applicable to many areas of science and scholarship,
and should be considered within the core of logic.
Whether this core material should be covered in one course or a
sequence of two or more courseswould depend on many
parameters: the backgrounds and abilities of students, the
length of the course, and the depth one wanted to go into the
various topics, for example. These are matters which will have
to be settled at the local level.
Beyond this core material, there is additional material which
should be made available to all students.

32. Logic education for philosophers: a case in Japan ASL questionnaire
ASL guideline 2004
Recommendations for advanced post-secondary education (cont’d)
Institutions of higher learning should also offer courses which
include the following material within their scope.
An introduction to proof theory (Natural Deduction, the
Gentzen Hauptsatz, Herbrand’s Theorem, for example).
Some additional model theory (e.g., the L´wenheim-Skolem
o
theorems for countable languages, the decidability of the theory
of dense linear orderings, the non-expressibility of various
mathematical notions in first-order logic, non-standard models
of arithmetic).
Some additional set theory (some cardinal and ordinal
arithmetic, a discussion of the axiom of choice).
An introduction to computability theory (some machine model
of effective computability, Church’s Thesis; absolutely
unsolvable problems; the undecidability of validity).

33. Logic education for philosophers: a case in Japan ASL questionnaire
ASL guideline 2004
Recommendations for advanced post-secondary education (cont’d)
Institutions of higher learning should also offer courses which
include the following material within their scope.
An introduction to other kinds of logic. Just which would
depend on the interests of the faculty in question.
Some examples include intuitionistic logic, higher-order logic,
modal logic, temporal logic, infinitary logic, and substructural
logics.
An introduction to uses of logic in computer science (e.g.,
unification and the resolution method and their connections to
PROLOG, and the λ-calculus and its connections to LISP in
particular and computation in general).

Faculty comment from questionnaire
Active learning or practice sessions desired
In my student days, there were few logic textbooks. No practice
sessions. I just took notes and at only some occations I
answered questions when I was pointed. Homework every week
or practice sessions will train students more.

There is no connection between logic education and math
education. We should have been taught first-order logic before
analysis in the first-year of college [i.e. real-number analysis,
which requires the ϵ − δ argument]

Need a full-semester or year-long course even for a single topic
No prerequisite system.
How to make it teacher-proof?
Kyoto students have better math skills?

institutional problems and budgetary problems
Such problems are not specific to logic but common to fields without
department-level organization, such as statistics.
Lack of course numbering system: no standard curriculum, no
prerequisite description. Transfer is exceptional.
Few universities offer sound classes of logic.

Logic specific problems?
Training of philosophers of science has common problems
interdisciplinary area which requires knowledge and skills in
natural science/math
most students learn those areas only for university entrance
examination for humanities:
most national universities: multiple choice test of math up to
high school Math II (without differentiation/integration but
introduction) and introductory natural science.
Tokyo and Kyoto are better as they have written exams of math
even for humanities and social science.
private universities: math is required only in exceptional cases
for humanities.

cf. Ishiguro’s comments on British education
system
”I am sorry for those excellent philosophers not to have a chance to
learn mathematics after they chose their subjects when they were 11
years old in a grammar school. They did not even know much about
elementary calculus. I really appreciate Japanese education after
WWII, where even girls learnt mathematics!”

no need of philosophers any more?
Naturalization of philosophy. Methodology of individual science,
mostly experimental
Logic as a tool of mathematicization of philosophy: it was the
program of analytic philosophy

University or academic associations?
can the organization offer advanced courses?
sustainability of part-time lecturer system

Should logic stay in philosophy? If yes, how?
Already shifted to CS/mathematics?
What research areas of philosophy require logic?
historical investigation of philosophy of logic and others, i.e.
analytic philosophy of the 20th century
philosophical logic
foundation of mathematics, or philosophy of mathematics
any others?
