If a concept lacks an essence, nothing will ever be found that completely fits that concept. If you are lacking in the concept of human being, it will immediately expose that you are something individual, something that cannot be expressed by the term human being, thus, in every instance, an individual human being.
Max Stirner
The concept of need is often looked upon rather unfavorably by economists, in contrast with the concept of demand. Both, however, have their own strengths and weaknesses. The need concept is criticized as being too mechanical, as denying the autonomy and individuality of the human person, and as implying that the human being is a machine which "needs" fuel in the shape of food, engine dope in the shape of medicine, and spare parts provided by the surgeon.
Kenneth Boulding
Every word instantly becomes a concept precisely insofar as it is not supposed to serve as a reminder of the unique and entirely individual original experience to which it owes its origin; but rather, a word becomes a concept insofar as it simultaneously has to fit countless more or less similar cases — which means, purely and simply, cases which are never equal and thus altogether unequal. Every concept arises from the equation of unequal things. Just as it is certain that one leaf is never totally the same as another, so it is certain that the concept "leaf" is formed by arbitrarily discarding these individual differences and by forgetting the distinguishing aspects.
Friedrich Nietzsche
We need tremendous energy to bring about a psychological change in ourselves as human beings, because we have lived far too long in a world of make-belief, in a world of brutality, violence, despair, anxiety. To live humanly, sanely, one has to change. To bring about a change within oneself and therefore within society, one needs this radical energy, for the individual is not different from society — the society is the individual and the individual is the society. And to bring about a necessary radical, essential change in the structure of society — which is corrupt, which is immoral — there must be change in the human heart and mind. To bring about that change you need great energy and that energy is denied or perverted, or twisted, when you act according to a concept; which is what we do in our daily life. The concept is based on past history, or on some conclusion, so it is not action at all, it is an approximation to a formula. So one asks if there is an action which is not based on an idea, on a conclusion formed by dead things which have been.
Jiddu Krishnamurti
In spite of the universalistic spirit of the monotheistic Western religions and of the progressive political concepts that are expressed in the idea "that all men are created equal," love for mankind has not become a common experience. Love for mankind is looked upon as an achievement which, at best, follows love for an individual or as an abstract concept to be realized only in the future. But love for man cannot be separated from love for one individual. To love one person productively means to be related to his human core, to him as representing mankind. Love for one individual, in so far as it is divorced from love for man, can refer only to the superficial and to the accidental; of necessity it remains shallow.
Erich Fromm
Whatever concept one may hold, from a metaphysical point of view, concerning the freedom of the will, certainly its appearances, which are human actions, like every other natural event are determined by universal laws. However obscure their causes, history, which is concerned with narrating these appearances, permits us to hope that if we attend to the play of freedom of the human will in the large, we may be able to discern a regular movement in it, and that what seems complex and chaotic in the single individual may be seen from the standpoint of the human race as a whole to be a steady and progressive though slow evolution of its original endowment.
