The question that is nagging me is that if romantic love happens after an individual achieves a certain degree of financial success or any condition that may be desirable, is such a love more love like, than love that has very few conditions? I would like to read on this and related topics. Can someone refer me to a book or source that discusses love and its conditions?
It is unfortunate that "love" in English has so many meanings, with at least these three:
- agape - willing the good of another person independent of one's self.
- eros - attraction (from where we get "erotic")
- philios - "brotherly love" - something like friendship or love for the mutual benefit of two people
To address your question, it seems that you may be equating different kinds of love that ought not to be - one type isn't more "real" than another, although in some cases may be exhibiting one particular type better or worse.
The IEP has a good article giving a high-level overview of the philosophy of love, and it suggests these readings:
- Aristotle Nicomachean Ethics.
- Aristotle Rhetoric. Rhys Roberts (trans.).
- Augustine De bono viduitatis.
- LaFallotte, Hugh (1991). "Personal Relations." Peter Singer (ed.) A Companion to Ethics. Blackwell, pp. 327-32.
- Plato Phaedrus.
- Plato Symposium.
- Scheler, Max (1954). The Nature of Sympathy. Peter Heath (trans.). New Haven: Yale University Press.
To paraphrase your question: Is conditional love more love-like than unconditional love?
I believe the short answer is "no" since, as has been pointed out, many different definitions of "love" exist. And by what measure could one form be more love-like than another?
The concept of pragmatic love or pragma that may fit what you ask about. It is an ancient concept. One can imagine all sorts of conditions between partners engaging in pragma.
Pragmatic lovers want to find value in their partners, and ultimately want to work with their partner to reach a common goal. The practicality and realism of pragmatic love often aides longevity of the relationship, as long as common goals and values remain shared for the duration.
Unconditional love could refer to agape.
Pragma and agape are neither more love-like than the other. Both fall under what we refer to as "love." Different authors define "love" very differently. There seems to be no centrality to "love."
