wn: unless indeed a Reverend Fellow of
the Royal Society may be held to be the fool who said in his heart, etc.,
etc., if his contributions to the _Philosophical Transactions_ go no higher
than _nature_. The following anecdote is well known in Paris, but has never
been printed entire. Laplace once went in form to present some edition of
his "Systeme du Monde" to the First Consul, or Emperor. Napoleon, whom some
wags had told that this book contained no mention of the name of God, and
who was fond of putting embarrassing questions, received it with--"M.
Laplace, they tell me you have written this large book on the system of the
universe, and have never even mentioned its Creator." Laplace, who, though
the most supple of politicians, was as stiff as a martyr on every point of
his philosophy or religion (e. g., even under Charles X he never concealed
his dislike of the priests), drew himself up and answered {2} bluntly, "Je
n'avais pas besoin de cette hypothese-la."[2] Napoleon, greatly amused,
told this reply to Lagrange, who exclaimed, "Ah! c'est une belle hypothese;
ca explique beaucoup de choses."[3]

It is commonly said that the last words of Laplace were, "Ce que nous
connaissons est peu de chose; ce que nous ignorons est immense."[4] This
looks like a parody on Newton's pebbles:[5] the following is the true
account; it comes to me through one remove from Poisson.[6] After the
publication (in 1825) of the fifth volume of the _Mecanique Celeste_,
Laplace became gradually weaker, and with it musing and abstracted. He
thought much on the great problems of existence, and often muttered to
himself, _Qu'est ce que c'est que tout cela!_[7] After many alternations,
he appeared at last so permanently prostrated that his family applied to
his favorite pupil, M. Poisson, to try to get a word from him. Poisson paid
a visit, and after a few words of salutation, said, "J'ai une bonne
nouvelle a vous annoncer: on a recu au Bureau des Longitudes une lettre
d'Allemagne annoncant que M. Bessel a verifie par l'observation vos
decouvertes theoriques sur les satellites de Jupiter."[8] Laplace opened
his eyes and answered with deep {3} gravity, "_L'homme ne poursuit que des
chimeres_."[9] He never spoke again. His death took place March 5, 1827.

The language used by the two great geometers illustrates what I have said:
a supreme and guiding intelligence--apart from a blind rule called _nature
of things_--was an _hypothesis_. The absolute
