Generosity is the desire for love, joy and sharing. It is the virtue of giving.
We act according to and in conformity with the demands of love, morality and solidarity, offering to the other what is ours and is lacking.
It is such a great virtue because it is usually very weak in each of us and selfishness is always stronger.
Like all virtues, generosity is plural both in its content and in the names that are given to it or that are used to designate it. Allied to the courage it can be heroism, allied to justice it becomes equity, allied to compassion it becomes benevolence, allied to mercy it is indulgent and allied to gentleness it is called goodness.
Generosity is opposed to hatred, contempt, envy, anger and also to indifference.
Only in the absence of love do we need it, so we need it almost always.
