The importance of pheromones shouldn’t be underestimated when discussing human attraction, but surely there’s more to love than a mere chemical response — right?

Those of you who espouse a purely scientific view of the matter would say no, it really does boil down to those chemicals intermingling in a compatible manner; romantics, on the other hand, are likely to brush that explanation aside. The sense that love can’t always be explained rationally is part of what makes it love, you would argue, and attempting to define everything is to miss out on one of life’s most magical experiences.
