Cicero says, "Nemo, fere saltat sobrius, nisi forte insanit, neque in solitudine, neque in convivio honesto." That is, "No man dances, in private, or at any respectable entertainment, except he be drunk or mad." We collect at least from the above statement, that people of old, who were celebrated for their wisdom, came to very different conclusions with respect to the propriety of the encouragement of this art.
Those nations among the ancients, which encouraged dancing, did it upon the principle, that it led to an agility of body, and a quickness of motion, that would be useful in military evolutions and exploits.

Hence swiftness of foot was considered to be an epithet, as honourable as any that could be given to a warrior.
The moderns, on the other hand, encourage dancing, or at least defend it upon different principles.

They consider it as producing a handsome carriage of the body; as leading to a graceful and harmonious use of the limbs; and as begetting an erectness of position, not more favourable to the look of a person than to his health.
That dancing produces dispositions of this sort cannot be denied, though certainly not to the extent which many have imagined.

Painters, who study nature the most, and are the best judges of the appearance of the human frame, are of opinion, that modern dancing does not produce natural figures or at least such as they would choose for their respective compositions.

The military exercise has quite as great a share as dancing in the production of these dispositions.
