CONDILLAC
SENSATIONALISM
Born in Grenoble, the
son of a lawyer, Étienne de Condillac was educated at the seminary of
Saint-Sulpice and at the Sorbonne, where he studied theology. He was ordained in 1740, but devoted his life
to philosophy rather than to his sacerdotal duties. He was in close touch with the leading figures
of the French Enlightenment and was a friend of Rousseau. In 1758 he became tutor to Ferdinand of
Parma, returned to France in 1767, and
was elected to the Académie Française the following year. He died in the Abbey of Flux near Beaugency.
LANGUAGE
[1] In his Essay on the Origin of Human Knowledge Condillac supposed that language came into being
'naturally' in the context of man's emerging rationality. We receive sensations and thence ideas. We reflect on this and link them together by using signs or symbols [a]. A "well-constructed language" is necessary for
human thinking. However, in his later Treatise on Sensations [I, iv] he argues that even people limited to
one sense, for example, smell can come to the idea of number (up to a maximum
of three) even before they acquire language. He would seem therefore now to admit the possibility of a prelinguistic intelligence [b] though language is needed if our mental
life is to develop fully.
METHOD/ KNOWLEDGE
[2] [Treatise on Systems] Condillac rejects the metaphysical rationalists' 'spirit of systems' (esprit
de systéme), which employs deduction of conclusions from the
definitions or axioms such philosophers suppose to be necessary truths about
the world; for definitions, he says, are only about meanings of words. But he does not reject systematization (esprit systématique), which
involves the breaking down of what is given to us in sense-experience and the
orderly arranging of the various parts of a 'science' so as to make explicit
the relations holding between them. He thus accepts the methods of
'analysis' and 'synthesis' provided they utilize sensory phenomena and not
the principles, definitions, and axioms of mathematics [a].
[3] The starting-point for knowledge, indeed the whole of one's
psychological or mental life is, according to Condillac, sensations (and their association) [see Treatise on Sensations] [a]. And
by means of a 'thought-experiment' he tries to show that all the operations of
our minds can be understood as deriving from any of the five senses. He supposes [I, i] man to be a marble statue
possessing only the sense of smell, say of a rose. By 'attending' to his sensations he will
acquire both memory impressions of variable strengths and liveliness and
judgements (through the comparing of memories of smells of different
flowers. The feeling of need to return
to a pleasant state will produce desire and thence awareness of will [I, iii]. Similar considerations apply to each of the
other four senses. By separating and reflecting on
disparate sensations we can form abstract ideas [b]. Condillac regards the sense of touch as
important in that it both clarifies and fixes our visual impressions of space and first gives us the idea of
externality [I, vii, xi, xii; II, v]. We do not know that there are external
things. However, in discovering
externality we show that our sensations are caused; and we assume thereby that
there are existent objects outside us to which we attribute properties,
including extension, put together by the mind [c]. But we can have no certainty of this [IV,
v]. As for the mind itself this can be known only in or
through its modifications or transformed sensations and memory impressions [I, vi] [d].
PSYCHOLOGY/ ETHICS
[4] From the concept of 'attention'
(to one's sensations) Condillac develops the concept of 'uneasiness' (inquiétude) as the basic motivating principle underlying all mental
experience [a] (sense-perception
includes understanding, feeling, desiring, fearing, willing, etc.) [see 'Reasoned Excerpt ']. By 'uneasiness' he means roughly a 'felt
need' to bring about some change in one's condition, be it intellectual,
physiological, or emotional. His position can be described as
'voluntaristic'; he thinks of the soul as an active and free spiritual unifying
principle though nevertheless psychical phenomena are to be understood as deriving from sensations [b]. Morality too arises from
feelings (of pleasure and pain) and the will, but is ultimately underpinned by
God [c].
CRITICAL SUMMARY
Condillac's philosophy may be understood as
having taken to their logical conclusion the assumptions and methods of
Lockean/ Newtonian empiricism, both our knowledge of the world and the
activities of the human mind being accounted for in terms of sensations. Thus his philosophy was to provide a basis
for a 'science of man' [a]. Several original features in his
thought should also be mentioned: (a) his emphasis on the primacy of the sense
of touch in relation to the concept of externality; (b) his view of the active,
unitary, spiritual soul as exhibiting 'voluntarist' tendencies (the concept of
'uneasiness'); (c) his stressing of the important role played by language in
our thinking and in later work his suggestion that intelligence is prior to
language though requiring it for its development. Thus Condillac was not strictly a
materialist. Nevertheless, to the extent
that his theory of knowledge is grounded in and confined to sensations he cuts
himself off from the external world and is restricted to probabilism. Moreover, his sensationalism is not easily
reconcilable with the spiritualist aspect of his account of mind.
Condillac: Essai sur l'origine des connaissances
humaines (1746) (Essay on the Origin of Human Knowledge); Traité
des systémes (1746, 1771) (Treatise on Systems); Traité des
sensations (1754) (Treatise on Sensations); the 1778 edition contains the 'Extrait
raisonné'. The Essay has
been translated by H. Aarsleff; and there is a translation of the Treatise
on Sensations by G. Carr. His
writings as a whole are collected in Philosophical Writings of Etienne
Bonnot, Abbé de Condillac, (ed.) L. Erlbaum; see also R. Lefèvre, Condillac [selections].
