I would like to talk about the vitalist notion of energy in a very broad sense - qi, prana, "animal magnetism" and so on.
First off - how would you try and "define" it? I know, it's terribly hard to come up with reasonable definitions for such broad terms in the realm of spirituality and esotericism, but let's try.
Second, to me it is obvious that this "energy" cannot be the same as physical energy in the scientific sense, and that a lot of the claims made with reference to science in that regard are simply wrong. The "energy flow" I feel when I take a deep breath is clearly not the same thing as "
the quantitative property that is transferred to a body or to a physical system, recognizable in the performance of work and in the form of heat and light." I don't literally heat up with each breath, and the wave I feel is certainly not my cells using up oxygen to burn fat. There are a lot of psychological and physiological processes between the physical act an the way it makes me feel.
Third, you will often hear claims such as "everything is energy". I see a philosophical problem with that: "Everything" cannot be "one particular thing", because concepts make sense only in comparison to other concepts. (Strictly speaking, I think it is impossible to conceptualize "everything", but that's another topic which I think leads too far away from the energy issue.) You cannot have light without dark, and you cannot have energy without matter. You can say that matter is just a form of energy, but then I would challenge you to define energy such that it does not presuppose matter - which I think is impossible.
Or to put it another way: "Everything" is necessarily void of any attribute, apart from being, well, everything. If "everything is energy", then the word energy loses its meaning. It's just "everything". The same goes for "everything is spirit", "everything is god", "everything is love", etc. So what's your comment on that? Specifically, what is your counter-argument, if you disagree?
In Chemistry and Engineering there is what is called Free Energy. Free Energy is expressed by the equation; G-H-TS, where G is the Gibbs free energy, named after the Josiah Willard Gibbs, who developed the free energy equation in 1870. H is enthalpy, T is temperature in degrees Kelvin and S is entropy.
Enthalpy or H is the sum of a thermodynamic system's internal energy and the product of its pressure and volume. The calories in a liter of sugary soft drink at one atmosphere would be an example of enthalpy. Entropy is not free energy per se, since ST or entropy times temperature has the units of energy. T or temperature reflects the
kinetic energy of the vibrating and colliding
atoms making up a substance. Entropy is a state variable that defines the unique state of matter at given conditions of temperature and pressure. In that sense, entropy is similar to the thermodynamic information of the state of a system, which when combined with the kinetic energy of the atoms within that state; T, reflect a second aspect of free energy; quantum mechanical energy.
The entropy of water at 25C and 1 atmosphere is measured as 188.8 Joules/(mole K). Entropy by itself is not energy but when combined with the kinetic energy of individual atoms; temperature, it defines free energy. At absolute zero we get T=0K and there is no movement of free energy, but some state entropy will still exist. The negative sign connected to -TS reflect the second law where the entropy of the universe has to increase, thereby lowering system; universal, free energy.
Entropy is key to life. Since our body stays at constant temperature; 98.6F, and is composed of countless states of water, organics and ions, changes within entropy will reflect changes in local and global free energy, that we can feel and which can even alter our state of mind.
Neurons expend the lions share of their metabolic energy; 90%, pumping and exchanging ions. This sets the membrane potential for neutron firing, with neuron firing behind consciousness, thought and action.
The ion pumping and exchange, which requires so much neuron energy, lowers the entropy at the membrane by concentrating and segregating ions on the opposite sides of the membrane. Left to their own devices, these soluble ions in water like sodium and potassium want to blend, like salt dissolving in water. The neurons are reversing this natural path to disorder, to creates ionic order from chaos. This is lowering of the ionic entropy, increasing the stored free energy on the surface of the neurons; action potential; -T(-S)=+TS=+G
Since the second law states that the entropy of the universe has to increase, with the neurons deliberately going the wrong way, something has to give to satisfy the second law; neurons will have to fire, via brain waves and information transfer thereby blending the ions back to disorder. But the neuron is busy creating order again and again. The effect is like fountain of entropic potential, which by virtue of its connection to increasing complexity, makes the brain self evolving to higher states of complexity.
The branching structures of neuron axons and dendrites, needed for memory, form through changes in osmotic pressure. Osmotic pressure is one of the four colligative properties of matter.
Colligative properties are the physical changes that result from adding solute to a solvent. Colligative Properties depend on how many solute particles are present as well as the solvent amount, but they do NOT depend on the type of solute particles, although they do depend on the type of solvent.
Colligative properties like osmosis are not EM force dependent since osmosis is not dependent on the charge or lack of charge of the solute, but only on the total number of solute units in water, in any combination. Neuron branching, that reflects learning and forming of memory is not exactly connected to the EM forces. This is more connected to entropy where the increase in entropy is generating a force; osmotic pressure; force/area. This action of entropy was intuitively called the life force.
All cells from bacteria to complex cells such as the differentiated cells of the human body use ion pumping to set the stage for the life force; colligative property of osmotic pressure. The life force is a not an EM based force but an entropic force.
In an osmotic device, two chambers of solvent are separated by a semi-permeable membrane that allows the flow of the solvent but not the solute particles. Since water is continuous, if one side of the device has a higher concentration of ions, the ions would like to flow and blend to form a unified solution; concentration gradient. But since they cannot due to the membrane, the water will do it for the ions and flow toward concentrated ions to dilute these down, so they can spread out. Entropy is a system state variable. It generates pressure against gravity, by doing so. In the case of the neurons branches, the entropic pressure pushes branches through the fluids of the brain at atmospheric pressure, with the goal of increasing the entropy of the brain; higher state.
The highest state of the brain appears to be the thalamus located in the center of the brain. It is the most wired part of the brain, being like a central switching station that receives and output to all areas of the brain and spine; inner self. The ego is more within the cerebral matter. The modern state of the inner self is sufficient to support two centers of consciousness to help increase entropy; consciousness within the complexity of civilization.
