hard cases and easy cases? principles/rules/philosophy to determine your decisions in situations?? Grid lines vs. circles???

Yep all these are what im suppose to write for my philosophy essay by mon...which i haven started....which i only juz really read the question ytd night... you can say i didnt want to face the essay before ytd but when i read the question, i was like *stressed*!!! hahaz cuz i realize its not as straightforward as i thought it would be...and its not just writing about certain issues but i must create at least 4 hypothetical or real examples to define "grids vs. circles" (if you dun understand what is it, i wouldnt blame you hahaz and if you're interested to know more, pls consult me hahaz then i'll see if i really understand it =P )

yup so im listening to it while writing this blog hahaz oh my lecturer is talking about families - should we ban families (eliminate families) and eliminating nations...why?? so that we'll be impartial, like if your father commited a crime (touch wood!!), will you bring your father to court and ask the police to arrest him? piety fillial vs. justice...difficult choice, so eliminate the family, then, we'll all make decisions based on laws and regulations...but then...when you grow up, you'll know ppl, make friends, get married, then its a cycle again...even if you dont know your children, you have other ppl whom you care about. so by eliminating families and nation is not a solution...

ahhhh. if you dont understand what im writing about, please dun feel stress and think im crazy hahaz juz take it with a pinch of salt and for entertainment sake ya. or if it sets you thinking, thats even better =) and if you have any views bout wat i said pls tag, maybe you'll help me with my essay hahaz
