personally, i find that simply denominating sex as the common goal for which humanity should strive seems limited, a hampering logic, and quite frankly, it taints my human pride. we are not such savage beasts as to allow such carnal instincts to dominate our mentality- shameful it would be to pursue in life the moments chemical pleasure of intercourse- bearing in mind that when one pursues any such matter, they often are hence blinded to the myriad or remaining options and paths. Imagine, at the end of your life, in retrospect, you find that the entire environment which encompassed you was lost in the pursuit of sexual pleasure. i might only agree if by some means, you could convince me, and remove me from my stated obstinacy, that sexual goals are conducive to the development and progression of society- wherein we hope to further the thriving of the human race. or, perhaps, rephrase your meaning, for "sex" is simply so utterly limited and provides for very little speculation and lacks the dimensionality into which we should be able to delve on this matter. or, conclusively, perhaps the common goal is to understand each and every moment in which we live, thereby reaching for a moral definition which will prove unattainable, and which will cause us to forget the remaining eons of time, as we focus steadily and diligently in the past- if so, the human goal, if at all existent, is frivolous and futile.
