No one can give anyone else the gift of the idyll; only an animal can do so, because only animals were not expelled from Paradise. The love between dog and man is idyllic. It knows no conflicts, no hair-raising scenes; it knows no development.
The quote suggests that true idyllic experiences cannot be given from one person to another; they can only be found in the relationship between humans and animals. Animals, unlike humans, have not been removed from a state of purity and innocence, symbolized by Paradise. This purity allows for a love that is straightforward and uncomplicated.
Kundera highlights the bond between dogs and humans as a perfect example of this idyllic love. This relationship is characterized by harmony and a lack of conflict, providing a sense of comfort and simplicity that transcends the complexities of human interactions. It emphasizes that the love shared with animals remains untainted by the turmoil often present in human relationships.
