The Hedonic Calculus states that both pleasure and pain are intrinsic goods and evils, respectively.

Aristippus of Cyrene was the first philosopher to propose the Hedonic Calculus.

The goal of the Hedonic Calculus is to maximize pleasure and minimize pain.

Intrinsic goods are good in themselves, while extrinsic goods are good only as a means to something else.

Virtue is an intrinsic good because it is good in itself, regardless of its consequences.

Money is an extrinsic good because it is only good as a means to something else, such as buying food or shelter.

Whether or not it is possible to achieve a state of perfect happiness depends on the individual's circumstances and beliefs.

The Hedonic Calculus is not necessarily a selfish theory, as it is possible to pursue one's own pleasure while also taking into account the pleasure of others.

The Hedonic Calculus has been criticized by some philosophers for being too simplistic and for ignoring the importance of other factors, such as justice and virtue.

The Hedonic Calculus is still influential today, particularly in the fields of economics and psychology.
