In this quote, William Ellery Channing is suggesting that life has a higher purpose than simply looking for entertainment or amusement. He is stressing the value of discovering meaning and fulfillment in life, instead of simply delighting in short-term enjoyments. Channing thinks that life should be dealt with intent and purpose, striving towards a greater goal or supreme fulfillment. This quote acts as a reminder to not get caught up in superficial diversions, however to concentrate on the deeper meaning and function of our existence. It motivates us to look for and pursue what genuinely matters in life, instead of being content with simple amusement.
"Life is life - whether in a cat, or dog or man. There is no difference there between a cat or a man. The idea of difference is a human conception for man's own advantage"
