or painters, is it not obvious that, in order, to be happy, it is necessary to be initiated into the secrets of pleasure?  All men experience the craving for reproduction, as all feel hunger and thirst; but all are not called to be lovers and gastronomists.  Our present civilization has proved that taste is a science, and it is only certain privileged beings who have learned how to eat and drink.  Pleasure considered as an art is still waiting for its physiologists.  As for ourselves, we are contented with pointing out that ignorance of the principles upon which happiness is founded, is the sole cause of that misfortune which is the lot of all the predestined.

It is with the greatest timidity that we venture upon the publication of a few aphorisms which may give birth to this new art, as casts have created the science of geology; and we offer them for the meditation of philosophers, of young marrying people and of the predestined.

CATECHISM OF MARRIAGE.

XXVII. 
Marriage is a science.

XXVIII. 
A man ought not to marry without having studied anatomy, and dissected
at least one woman.

XXIX. 
The fate of the home depends on the first night.

XXX. 
A woman deprived of her free will can never have the credit of making
a sacrifice.

XXXI.  In love, putting aside all consideration of the soul, the heart of a woman is like a lyre which does not reveal its secret, excepting to him who is a skillful player.

XXXII.  Independently of any gesture of repulsion, there exists in the soul of all women a sentiment which tends, sooner or later, to proscribe all pleasure devoid of passionate feeling.

                               XXXIII. 
The interest of a husband as much as his honor forbids him to indulge
  a pleasure which he has not had the skill to make his wife desire.

XXXIV.  Pleasure being caused by the union of sensation and sentiment, we can say without fear of contradiction that pleasures are a sort of material ideas.

XXXV. 
As ideas are capable of infinite combination, it ought to be the same
with pleasures.

XXXVI. 
In the life of man there are no two moments of pleasure exactly alike, any more than there are two leaves of identical shape upon the same
tree.

XXXVII. 
If there are differences between one moment of pleasure and another, a
man can always be happy with the same woman.

XXXVIII. 

To seize adroitly upon the varieties of pleasure, to develop them, to impart to them a new style, an original expression, constitutes the genius of a husband.

XXXIX.  Between two beings who do not love each other this genius is licentiousness; but the caresses over which love presides are always pure.

XL. 
The married woman who is the most chaste may be also the most
voluptuous.

XLI. 
The most virtuous woman can be forward without knowing it.
