A Philosophical Aspect of Eating Food Animals and Food Plants

This study investigated the philosophical aspects of eating agricultural products (food animals and food plants), using the viewpoint of growth mechanics and symmetry. The results obtained were as follows. (i) Introducing growth mechanics into basic growth function gave not only a positive function (individual human body weight) but also a negative function (agricultural products whose weights were expressed using the human body weight). Those two functions resulted from symmetry about the differentiation of basic growth function that showed an accelerated increase. Symmetry and accelerated increase were considered physical laws that basic growth function showed. (ii) The negative value was interpreted as the disappearance of agricultural products by being eaten by the individual human. This was regarded as the symmetry breaking between humans and agricultural products. (iii) It was suggested that the thing similar to depriving animals and plants of lives occurred at the inside of the human body, in the human society, and in the universe. Gap–widening societies and wars were examples occurring in the human society. (iv) It might be impossible for humans to escape from those physical factors (symmetry breaking, accelerated increase) causing the deprivation activity
