What the
TOK Syllabus has to say about … Reason
Key Quotations:
·
‘It has been said that man is a rational animal. All my life
I have been searching for evidence which could support this.’ Bertrand Russell
(1950)
·
‘Lack of logic annoys. Too much logic is boring. Life
escapes logic, and everything built on logic alone is artificial and limited. Therefore
is a word that the poet must ignore, that exists only in the mind.’ Andre Gide
·
“Thinking is a form of feeling…feeling is a form of
thinking.” Susan Sontag
Overall Summary:
Reason is a way of knowing that involves different
elements. In a very general sense, reasoning is a collective endeavour by which
people construct meaning together by exchanging, modifying and improving their
ideas and opinions. When someone makes a claim to know, it is legitimate to ask
forreasons and to expect that these will be coherent. Arguments require
consistency. Reason is perhaps as present in everyday decision making and
problem solving as it is in mathematics, sciences and other areas of knowledge.
The requirements of logical validity and rigour serve these various purposes
In different degrees and in different ways, it is
arguable that reason has its place in many, if not all, areas of knowledge as
well as in the everyday experience of individuals and the groups to which we
belong. It may be worth considering how reason is used in these different
domains to discover and create, to articulate, to justify and assess knowledge
claims. For when disputes arise, what is at issue is not only the substance or
facts of the matter, but also the appropriateness of the reasons given for
acceptance of the facts, and the validity of the logical procedures used in
reaching the conclusion. The questions in this section probe the nature, value
and limits of reason, and the logic that many suppose is a shared standard of
evaluation.
Questions about … the Nature of reason
·
One of the roles traditionally attributed to reason is to
find balance or equilibrium between two extremes. Is this idea still relevant
as a description of the role that reason plays in the search for self-knowledge?
What does it mean for someone to be reasonable?
·
What is the difference between reasoning about means and
reasoning about ends? Is one more prevalent or more valuable than the other?
·
What is the role of reason in the creation and recognition
of patterns in nature and in social life?
·
Is reason purely objective and universal, or does it vary
across cultures? Is logic purely objective and universal?
·
Formal logic is the study of form in argument, irrespective
of the subject matter. Is it really possible to study the logic of an issue
independent of its content, and how beneficial is it to do so? Does the answer
to this question depend upon the subject matter under consideration? Does it
depend on the area of knowledge to which the subject matter belongs?
·
What is the relationship between reason as a way of knowing
and logic in its different forms (inductive, deductive, intuitive, natural)? Is it possible and worthwhile to “translate”
everyday arguments into formal logical structure, and what might be lost in the
translation? How does the commonsense use of “it’s logical”, meaning “it makes
sense to me”, differ from its technical meaning of “it has a valid argument
form”?
Questions about … Reason and knowledge
·
What possibilities for knowledge are created by reason? What
are the advantages of being able to reason about something rather than, say,
feeling something, dreaming about something, wishing something to be the case?
·
Does all knowledge require some kind of rational basis?
·
If knowledge claims cannot be rationally defended, should
they be renounced? Is the answer to this question dependent on the area of
knowledge of the claim?
·
Can reason on its own, independent of sense perception,
emotion and language, ever give us knowledge? Or are reason and language
inseparable in the quest for, construction and justification of knowledge?
·
What constitutes a good argument? What is the value of
learning to distinguish between valid and invalid arguments?
Questions about … the Strengths and weaknesses of
reason
·
What are the advantages of discriminating between valid and
invalid arguments, good and bad reasons, more or less persuasive reasoning,
both for the individual knower and for society?
·
Why are informal fallacies often plausible and convincing?
When, where and by whom are they formulated? Are there
circumstances under which the use of informal fallacies can be justified, for example,
in public advertising campaigns aimed at persuading us to donate money for good
causes (for example, humanitarian relief, children’s funds)?
·
How can beliefs affect our capacity to reason well and to
recognize valid arguments? Can they affect a person’s capacity to distinguish
between fallacy, good argument and rationalization? What is the difference
between a rational argument and a rationalization?
·
What, if any, are the advantages of expressing arguments in
symbolic terms? Are the ambiguity and vagueness of conventional language
eliminated by this formulation?
·
Are there some parts of human life or experience where
reason has no real function?
Links to the Areas of Knowledge
·
How does the role of reason compare with the roles of the
other ways of knowing? Why might some people think that reason is superior, and
what consequences does holding this position have for the knowledge pursued and
the methods considered appropriate in the pursuit?
·
Does the role of reason affect the degree of certainty in,
or the social status of, the various areas of knowledge? What are the
implications of the answer to this question when disputes arise among practitioners
and between cultures?
·
Attempts have been made to identify universal, self-evident
and incontrovertible laws of logic, such as the law of identity (for example,
“an apple is an apple”) or the law of non-contradiction (for example, “nothing
can be an apple and also a non-apple”). Are these actually laws in the
scientific sense of the term, or are they axioms?
·
How do logical axioms compare with axioms in mathematics, and
with the underlying beliefs we take for granted in other areas of knowledge?
·
What is the role of reason in ethical principles and their
justification? Is reason more important to acting morally than other ways of
knowing?
