  During the querelle des infiniment petits, Leibniz wrote several texts to
justify using Differential calculus among Parisian savants. However, only three
were published. Among these publications, ''Sentiment de Monsieur Leibnitz''
had a peculiar destiny. Although we are aware of the manuscript (Gotha FB A
448--449, Bl. 41--42), it is only recently that we have identified a copy of
its impression in the British Library catalogue. This copy was printed in 1706
together with writings by other mathematicians united in the defence of the new
calculus -- Joseph Saurin, Jacob Hermann and the Bernoulli brothers. Recently
published epistolary exchanges indicate that Jean-Paul Bignon, at the time
director of the Royal Academy of Sciences, in order to calm down the
institution, had prohibited this publication and confiscated the prints.This
article examine the epistemological and institutional issues at stake in
''Sentiment de Monsieur Leibnitz''.
