"What life and society require of each of us is a constantly alert attention, that discerns the outlines of the present situation, together with a certain elasticity of mind and body to enable us to adapt ourselves in consequence." [Footnote: Laughter, p. 18 (Fr. p. 18).] The lack of tension and elasticity gives rise to mental deficiency and to grave inadaptability which produces misery and crime. Society demands not only that we live but that we live well. This means that we must be truly alive; for Bergson, the moral ideal is to keep spiritually alert. We must be our real, living selves, and not hide behind the social self of hypocrisy and habit. We must avoid being the victims of mechanism or automatism. We must avoid at all costs "getting into a rut" morally or spiritually. Change and vision are both necessary to our welfare. Where there is no vision, no undying fire of idealism, the people perish. Resistance to change is the sin against the Holy Spirit. Bergson is opposed to the conventional view of morality as equivalent to rigidity, and grasps the important truth that if morality is to be of worth at all it must lie not in a fixed set of rules, habits, or conventions, but in a spirit of living. This is of very great ethical importance indeed, as it means that we must revise many of our standards of character. For example, how often do we hear of one who, holding an obviously false view long and obstinately, is praised as consistent, whereas a mind which moves and develops with the times, attempting always to adjust itself to changing conditions in its intellectual or material environment, is contemptuously dubbed as "changeable" by the moralists of rigidity. We must, however, learn that consistency of character does not mean lack of change. Stanchness of character is too often mere obstinate resistance to change. We must therefore be on our guard against those who would run ethics into rigid moulds, and so raise up static concepts and infallible dogmas for beliefs or action. Change must be accepted as a principle which it is both futile and immoral to ignore, even in the moral life. This does not mean setting up caprice or impulsiveness, for in so far as our change of character expresses the development of the single movement of our own inner life it will be quite other than capricious, but it will be change, and a change which is quite consistent, a creative evolution of our personality.
