I’m not sure where that quote, “All’s fair in love and war” originated. I couldn’t find a clear source for the quote and it has been used for centuries. I don’t subscribe to the sentiment. I tend to agree more with “All’s well that ends well,” which may or may not have been first written by William Shakespeare.
Venus energy most closely represents love and Mars war. Venus denotes who and why we love and Mars represents how. The Venus of myth is not particularly moral in the common sense of the word, neither is Mars. They’re not immoral, against moral sense, but rather amoral, unconcerned with morality in their pure form. Morality is the realm of one’s personal values, represented by the 2nd house (which is ruled by Venus), rules (Saturn and the 10th house) and the philosophies we adhere to (Jupiter and the 9th house).
I have Virgo on the 2nd house cusp and tend to nitpick this type of extreme statement. I automatically question any maxim that starts with all, every, always or never, but that’s just me and my own personal value system.
For examining this type of proverbial wisdom, one that deals with Venus and Mars energies, it’s also helpful to assess the planets that aspect your own Venus and Mars. My Venus and Mars are very martial, warlike in their placements and aspects, but they’re both tied to Saturn (restriction). So while I’m interested in such statements I feel the need to run them past my personal rulebook first.
Is all fair in love and war? How does your answer reflect your values and your astrology?
