similarity of philosophy

In "Ode on the Death of A Favorite Cat Drowned in A Tub of Goldfishes," the cat was dead for her desire, unlike the duke and Porphyrias' "lover", who killed their women for desire of possessing. 
In the 4th stanza, it's said that the cat couldn't resist fish as female couldn't resist gold. I think that it's no wrong to like gold, but if one only care about this kind of valuable things, he/she is a superficial person. The cat would die because she wasn't satisfied with what she had, such as the vase. 
Actually speaking, it's not totally wrong not being satisfied with everything, and desire, either. It's known that human's technical developments and living improvements are depended on the dissatisfaction of people. Only if we know where we are (our capacity) can we not run the risk of being dead. 
"An Essay on Man" has a similar point as the last poem that I mentioned. The 2nd line of the 10th section, "Our proper bliss depends on what we blame". Also, this poem tells us to submit all kinds of things and the two opposite aspects of things. 
There are natal and mortal hour, discord and harmony, for example. "Whatever IS, is RIGHT" should have a sort of philosophy, and the explanations of the meaning differ from how we view the word "RIGHT." If "RIGHT" is the same with "TRUE", I'll explain this sentence that if there's no "EVIL", how can we tell "GOOD" from "EVIL"? Then come to a conclusion that whether it is positive or negative in our mind, it is RIGHT. 
The 1st section of this poem asserts that "The proper study of mankind is Man." I think that means even thought it was God that created Man, it is Man to decide either way or both way (in a middle state) he will be. The line "Born but to die, and reasoning but to err" somehow impressed me most. I think Man tries his best to make the decision, which is the best in his mind. It is this decision that differs one's life.
