MATHEMATICS OF PASSION. 
S51 
Some time ago some physicians of the Institute, who dreamed 
of no mischief, and especially not of laboring for the great glory of 
passional analogy, occupied themselves in amusing experiments 
upon the different properties of the yellow ray. They were com- 
pletely ignorant that passional analogy had decreed the functions 
of generative ray to the yellow ray. They have discovered that 
no ploM could fructify except under the action of the yellow ray ; 
and this fact, asserted a priori by passional analogy with that tone 
of authority which characterizes it, has remained, an acquisition of 
science^ like the existence of the planet Leverrier — like the exist- 
ence of the planets called telescopic, wdiich it had also announced. 
I established in 1845, in the columns of a daily paper, the iden- 
tity of character between the rat and the barbarian. I had proved 
that the two devastating scourges corresponded in history with rig- 
orous exactness, that every invasion of barbarians had deposited its 
special rat upon the invaded soil. 
A learned physician of the French Institute — a more than Euro- 
pean reputation — Doctor Lalleraand — has resumed this thesis in 
April, in 1847, in the Revue Independante, and it is very probable 
that the illustrious doctor had no knowledge of my work^ since he 
has not cited it. 
And between ourselves, gentlemen, who make yourselves merry 
at my expense, he will laugh best who laughs last ; for here comes 
in favor of passional analogy a third attestation far beyond the oth- 
er two in frankness and in authority. 
Still another prince of official science — a most illustrious mathe- 
matician, one of the glories of the French Institute — a pious man, 
who dares to say (November, 1845) in full session of the Academy : 
The Passions are forces subjected to the laws of Mathematics i 
the play of these forces constitute Passional Mechanics ! 
The young person who renounces her brilliant future of happi- 
ness and of family prospects, to consecrate herself to the repulsive 
service of the ^lok, obeys a calculable force, follows a resultant ! 
The play of the Passions constitutes Passional Mechanics. 
What more, than this have we said ? 
The young girl who renounces her future of happiness and of 
Love, follows a resultant (tension of Unityism). What say you
