This notion may seem mundane at first but scientist/theologian Emanuel Swedenborg took this idea much further by suggesting that we are what we digest. After all, we are obviously not what we eliminate through our bladder and large intestine.
We all possess different blood chemistries. Why? Swedenborg claimed that our loves, affections and desires determine what our digestive systems metabolize (and becomes a part of us). In other words, the blood demands those substances, which bring its chemistry into perfect harmony with our passions. (This is why we use such hematologic phrases as “bad blood” or “cold-blooded” or “red-blooded” to describe a person’s inner character.) Such bio-agreeability is necessary for anything to enter into and maintain the fabric of our life. Foodstuffs and substances, which do not resonate with (correspond to) our passions are rejected and jettisoned. No two people share the exact kinds of love or leanings. Our subjective and personal love is how we form our individuality.
Love is more than a romantic term—it is life itself.
Neuro-scientifically speaking, Swedenborg claimed that the involuntary part of the human mind and nervous system brings the corporeal or bodily machine into compliance (correspondence) with the various psycho-states of the human voluntary mind and its animus (affection).
Swedenborg also included the substances that our lungs and skin pores bring in from the circumfluent atmosphere as a second kind of food. We each take in different cosmic substances from the air, according to our subjective likes and dislikes (Again, derivatives of love).
Finally, Swedenborg added that sensory impressions (information) streaming into our five senses from the outside world are a third kind of food. It is well known that information and knowledge is “brain food” and that we each seek the information that we most value (love) but we rarely contemplate how these inputs of data affect the inner bio-fabric and quality of our spirits.
We form our deepest inner life and spiritual bodies (which survive physical death) from what we love. That is why love is the ultimate science!
