Love in philosophy - philia - is not eros, which your post seem to indicate. It is affection for another, non-relative person, and thus, freely chosen rather than instinctual. It would be akin to stating affection towards choosing wisdom, rather than desire for possession from lower emotion of eros.
Wisdom can be defined and assessed, as stupidity can be characterized and noted. To deny otherwise would defeat the purpose of any examination regarding man's behaviors and motivations. Denying the ability of man to segregate the wise and the fool would also make the very field of philosophy irrelevant and moot.
The Taoist way, being, and oneness all seem convincing, except to live one's life mired in search only is akin to prefer being in the subway for the sake of being in the subway. Search must have a purpose and a focus, just as the subway is but a means to an end.
