Editing Étienne Bonnot de Condillac (section)

==Biography==
He was born at [[Grenoble]] into a legal family, the youngest of three brothers. His two older brothers Jean and Gabriel took names associated with one of the family's properties at [[Mably, Loire]], and were each known as "Bonnot de Mably". Étienne identified with another property at [[Condillac, Drôme]], was known as "Bonnot de Condillac".  Like his brother Gabriel, Condillac took holy orders (1733–1740) at [[Saint-Sulpice church]] in Paris. He was appointed as Abbot of Mureau.{{sfn|Sturt|1911|p=849}}

Condillac devoted his whole life, with the exception of an interval as a court-appointed tutor to the [[Duchy of Parma|court of Parma]], to speculative thought. His works are:{{sfn|Sturt|1911|p=849}}

* ''{{lang|fr|Essai sur l'origine des connaissances humaines}}'' (1746); 
* ''{{lang|fr|Traité des systèmes}}'' (1749); 
* ''{{lang|fr|Traité des sensations}}'' (1754); 
*''{{lang|fr|Traité des animaux}}'' (1755); 
* a comprehensive ''Cours d'études'' (1767–1773) in 13 vols., written for the young [[Duke Ferdinand of Parma]], a grandson of [[Louis XV of France|Louis XV]]; 
* ''{{lang|fr|Le Commerce et le gouvernement, considérés relativement l'un a l'autre}}'' (1776); and two posthumous works, 
* ''{{lang|fr|Logique}}'' (1781) and the unfinished ''{{lang|fr|Langue des calculs}}'' (1798).

In [[Paris]], Condillac was involved with the circle of [[Denis Diderot]], the philosopher who was co-contributor to the ''[[Encyclopédie]]''. He developed a friendship with [[Jean-Jacques Rousseau]], which lasted in some measure to the end of his life. It likely started when Rousseau was a tutor to two of his brother Jean's sons in [[Lyon]]{{sfn|Sturt|1911|pp=849–850}}—Jean Bonnot de Mably was then provost of the police and known as Monsieur de Mably.

Condillac's relations with unorthodox philosophers did not injure his career. He had already published several works when the French court sent him to [[Parma]] to educate the orphan duke, then a child of seven years.{{sfn|Sturt|1911|p=850}}

On his return from Italy, Condillac was elected to the [[Académie française]] in 1768. Contrary to the popular idea that he attended only one meeting, he was a frequent attendee until two years before his death. He spent his later years in retirement at Flux, a small property which he had purchased near [[Beaugency]] on the river [[Loire]]. He died there on 2{{sfn|Sturt|1911|p=850}}<ref name=bd/> or 3<ref name="newadvent.org"/><ref name="Stanford"/> August 1780.
