The word “Individuality” is derived from the Latin root, “individuous”—in (not) dividuus (divisible). The individual is unique, not further classifiable—it is what it is. An individual is that which is indivisible, indivisible not in the sense that it is incapable of being divided into parts but that it cannot be so divided in its nature and remain what it is. Essentially an individual is one—not as the numerical concept of the one but as the Greek “monas” or unity and by virtue of its oneness is distinct or simple. Individual is a distinct and indivisible entity, uniting within itself, all possible modes of unity-unity of intrinsic form, cause, purpose and action.
Human individuality is the state or condition of subsisting as an individual in terms of persistent self-conscious identity. In the process of the emergence of consciousness there is formed out of mental, vital and physical experience, an integrating core, a centralisation of surface-consciousness. It is this integrating core of conscious experience which is the ego of a particular being and it is the practical constitution of consciousness which is referred to in common parlance as individuality.
Individualisation is the highest expression of existence just as, Personality is the highest expression of individuality. Instead of an unformed and unconscious mass, one has to become consciousness, cohesive, individualised, that which exists by itself and in itself, independently of its surrounding that which can hear, read, see anything and will not change because of that. It receives from outside only what it wishes to receive. It rejects automatically what does not agree with its purpose, nothing can leave any impression upon it, unless |t wishes to have the impress. It is thus that one begins to be individualised.
What is the underlying reason behind the appearance of this individual variety in spite of individuals being capable of being grouped in classes? The answer comes from a master mind—Each man belongs not only to the common humanity but to the Infinite in himself related to the master mind and is therefore unique. Infinite is capable of producing infinite diversities in unity; and unity in diversity seems to be the master plan of creation. The concept of individuality leads us to the concepts of personality and constitution. Personality, the highest expression of individuality, is a pattern of being marked out by a settled combination of fixed qualities, a determined character. This term, personality is also used to express the continuance of a person’s distinguishing qualities, of one’s personal identity in spite of bodily and mental changes. It is because of this individual personality we come across with individual constitution which is manifested by the inherent tendency to respond automatically along certain qualitatively predetermined characteristic response-patterns in identical situations. Constitutional differences are differences of these response-patterns compared in identical situations. In other words, constitution is that aggregate of hereditary characters influenced more or less by environment which determines the individual’s reactions, successful or unsuccessful, to the stress of environment.
As homoeopathy is based on individualisation of diseased persons and drugs it has to take note of the concepts of individuality, personality and constitution, but always taking into account the group aspect of location, sensation, modalities and concomittance.
