I had never noticed that all enjoyment spontaneously overflows into praise...the world rings with praise - lovers praising their (spouses), readers their favorite poets, walkers praising the countryside, players praising their favorite game - praise of weather, wines, dishes, motors, horses, colleges, countries, historical personages, children, flowers...The Psalmists in telling everyone to praise God are doing what all men do when they speak of what they care about.
I think we delight to praise what we enjoy because the praise not merely expresses but completes the enjoyment. It is its appointed consummation.
CS Lewis, as quoted in "Free of Me," Baker Books, page 137
