On Thursday it will be ‘Tu Be’Av’, or 15 Av, an obscure Jewish festival day when we highlight the importance of romantic love.

So I decided to research the phenomenon of love and see what modern science has to say about it.

Surprisingly, scientists have only relatively recently begun to research the human emotion we call love. The ancient Greeks grappled with love, but it was never high on their list of investigative topics. Poets and dramatists have always used love as a central motif for their creative work, but only to entertain, even if some of the output offered deep insights into this ubiquitous emotion and its effect on the human condition.

Scientific research is anything but poetic and creative. Nevertheless, the power of empirical data is indisputable, even if it is not warm and fuzzy.

What has emerged out of the research is that the love phenomenon is hard to define. A major study published in 1977 defined six separate categories of love, while a study published in 1984 defined love as one overarching emotion that has a number of practical applications, which can be broken down into eight definitions.

In short, the debate continues to rage.

Ultimately, love is easily understood in most of its guises, even by non-psychologists, and those not interested in statistics. The powerful feelings of closeness one has for a parent, for example, or for siblings, is intuitive at a very basic level. Each human being is instinctively eager to perpetuate his or her family, and emotional bonds with parents and siblings strengthen that commitment.

It is this primary drive that can also explain the deep love one has for one’s children. The emotional commitment to one’s offspring is what ensures that the primordial selfish instinct we are all born with is overridden, so that one prioritizes the needs of one’s child.

Some psychologists argue that this is a victory of one type of selfishness over another; the desire to outlive oneself through one’s progeny is just another form of narcissism.

The love between friends is also very deep. A friendship from early childhood that endures into adulthood is incredibly powerful. Shared experiences, loyalty, trust, and a level of affection that is lasting, define these relationships, and it has been proven that being with such a friend can be medically helpful when one is sick – decreasing high blood pressure, increasing dopamine levels, and reducing anxiety.

Once again, this kind of love makes perfect sense scientifically. It is bound up with the instinct for survival. Close friends help a human being survive, and the deeper the friendship, and the greater the number of such friends, the more chance one has of living a longer and healthier life.

The love that scientists really struggle with is the kind we all know as ‘romantic love’. Two people with no family ties, and no history together, fall in love.

Different cultures do it differently. Individualistic cultures, epitomized by the modern western world, place a stress on romantic love as a precedent to lifelong commitment, while cultures that focus heavily on collective thinking and community, including certain segments of the Jewish world, place such love second, focusing first on familial compatibility and financial considerations.

Whichever culture it is, romantic love must exist between the couple for their relationship to last.

The question is: why? Logic dictates that emotional compatibility should not be that important. If two individuals being with each other so that they can produce progeny makes sense ‘on paper’, why should romantic love, which is in reality a mere trifle and a distraction, play any role? And what of people who fall in love, get married, and don’t have children? Their love for each other can be equally intense and all consuming. How does that make any sense?

Although there are a number of interesting and even compelling theories, the question remains better than any of the answers, and outweighs all attempts to resolve it. So many romantic relationships that make no sense whatsoever endure only because of the bond of romantic love, while many others that work or should work at every other level, crash and burn because of the lack of romantic love between the two people involved.

In the final analysis, humanity might be better served without the burden and the complications of romantic love.

So what is the point? Why have we humans been hardwired to fall in love?

The Torah portion of Va’etchanan has an answer. In a directive we are all familiar with, we are instructed (Deut. 6:5): וְאָהַבְתָּ אֵת ה’ אֶלֹהֶיךָ בְּכָל לְבָבְךָ בְּכָל נַפְשְךָ וּבְכָל מְאֹדֶךָ – “you should love God with all your heart, with all your soul, and with everything you have.”

The commandment goes on to describe a mandated relationship that is intense, demanding, and all consuming. You are required to talk about God when you wake up, and when you go to sleep. You need to post signs of your love on your doorways, and wrap signs of your love around your arms and on your head. You need to talk about Him to your children.

You need to obsess about your relationship with God until it takes over your life. That is romantic love. We are commanded to have a lifelong love affair with God.

But how would we know what that means, or how to do it, if we have nothing to compare it with?

So God gave us a window into the relationship He wants with us. That window is the inexplicable bond between romantic lovers. A relationship that serves no other purpose than to demonstrate to us how much God wants us to love Him, and how much He loves us, even though it makes no sense.

When God tells us that “you should love God with all your heart, with all your soul, and with everything you have”, what he is really saying is “fall in love with Me – that is your purpose on this world.”
