CS Lewis, in his book Reflections on the Psalms, wrote about praise:
The world rings with praise—lovers praising their mistresses, readers their favorite poet, walkers praising the countryside, players praising their favorite game—praise of weather, wines, dishes, actors, motors, horses, colleges, countries, historical personages, children, flowers, mountains, rare stamps, rare beetles, even sometimes politicians or scholars.
I had not noticed how the humblest, and at the same time most balanced and capacious, minds praised most, while the cranks, misfits and mal-contents praised least.
I had not noticed either that just as men spontaneously praise whatever they value, so they spontaneously urge us to join them in praising it: “Isn’t she lovely? Wasn’t it glorious? Don’t you think that magnificent?”
…I think we delight to praise what we enjoy because the praise not merely expresses but completes the enjoyment; it is its appointed consummation. It is not out of compliment that lovers keep on telling one another how beautiful they are; the delight is incomplete till it is expressed.
