In Moliere’s The would-be invalid (1950), the protagonist explains the sleep-inducing effects of opium by invoking its dormitive virtue, and, upon hearing the explanation, the doctoral oral examining committee is wholly satisfied. Here, we have a classic case of tautology. From the Greek tautologos, for ‘redundant’, tautology refers to the representation of anything as the cause, condition, or consequence of itself: “…When
black, swan-like birds were discovered in Australia, there was doubt as to
whether they could be ‘swans’-for swans were supposed to be white. But
it was allowed that though they were black they were swans-so ‘black’
swan’ was not contradictory. Conversely, it is not tautologous to call a
swan white—though it would be if the quality of white-ness was a part of
the definition of a swan.” (Gregory (ed), 1987. p. 769). Whether
or not a proposition is deemed to be a tautology, then, depends on the
definition of concepts. Rachman (1980) provides us with an operational
definition of emotional processing as: “a
process whereby emotional disturbances are absorbed, and decline to the
extent that other experiences and behaviour can proceed without disruption”
(p. 51). For
a closer inspection of the nature of tautology, we need to first
understand the difference between analytic and synthetic propositions: For
Kant, propositions, or judgements, can be separated, basically, into two
kinds: analytic and synthetic. “In
all judgements in which the relation of a subject to a predicate is
thought…this relation is possible in two different ways. Either the
predicate B belongs to the subject A, as something which is (covertly)
contained in this concept A; or B lies outside the concept A, although it
does indeed stand in connexion with it. In the one case I call the
judgement analytic, and the other synthetic”. (in Korner, 1955.
p.18). An
example of an analytic judgement would be, “a rainy day is a wet day”.
Here the predicate ‘wet day’ is actually contained in the subject
‘rainy day’. Therefore, the proposition is an analytic one. The terms
are merely elucidated, and nothing further is learned. Furthermore, to
deny such a proposition would be contradictory. Kant says all such
analytic judgements are a priori. That is, the truth of them can be known
without reference to sensory experience. “A
rainy day is a cold day” however, is a synthetic judgement because the
predicate ‘cold day’ is not contained within the subject, ‘rainy
day’. So, synthetic judgements, “add to the concept of the subject
a predicate which has not been in any wise thought in it, and which no
analysis could possibly extract from it.” (in Ayer, 1971. p.71).
Judgements that are non-a priori, are called a posteriori judgements
and must necessarily be synthetic. For Kant, a third class of judgements
exists, that of synthetic a priori. That is, judgements whose denials are
not contradictory and whose truths are knowable without reference to
experience. Kant gives the mathematical example of 7+5=12 as a synthetic a
priori judgement. So,
the question becomes, ‘ is emotional processing, as defined above, an
analytic a priori judgement, and therefore a tautology?’ Or, more
precisely, ‘is the predicate of the proposition contained in the
subject?’ ‘[A] process
whereby emotional disturbances are absorbed, and decline to the extent
that other experiences and behaviour can proceed without disruption’
does not appear to be contained in the subject (emotional processing). The
predicate appears to be adding something more to the subject than could be
arrived at merely by analysing the subject alone. Conversely,
a criticism of tautology could be argued for, if this definition of
emotional processing was limited to, “[A]
process whereby emotional disturbances are absorbed”. Clearly, in this
instance nothing more is gained from the predicate that could not have
been deduced from an analysis of the subject in the proposition. However,
the operational definition provided by Rachman, is more akin to a possible
‘factual truth’, that may or may not be observed, than the ‘logical
truth’ of tautology, which is true in all cases. The concept of emotional processing, as defined here, may not be tautologous, per se, but does need to be placed under rigorous experimental scrutiny. As McNally (2001) makes clear, self-report measures are important in laying the foundation for experiments designed to test out mechanistic processes, but, used in isolation can lack the necessary scientific rigour. Referring to the catastrophic misinterpretation hypothesis in panic disorder, McNally (2001) points out that actually, “[p]utative panic “triggers” – bodily sensations interpreted catastrophically – may merely reflect the unfolding of an autonomous biological process. (P.516). Clearly, the dependent variables that index cognitive-emotional mechanisms, should be quantitative and publicly observable (e.g. reaction times).
