she had intended to refute the attacks upon marriage, contained in the works of George Sand, to whom she was intellectually no less than morally superior. Her nature was of rare endowment, moved by noble impulse, and yet allowing its due influence to reason. When she was beginning to study Positivism she wrote to me: ‘No one knows better than myself how weak our nature is unless it has some lofty aim beyond the reach of passion’. A short time afterwards, writing with all the graceful freedom of friendship, she let fall a phrase of deep meaning, almost unawares: ‘Our race is one which must have duties, in order to form its feelings’. With such a nature my Saint Clotilde was, as may be supposed, fully conscious of the moral value of Positivism, though she had only one year to give to its study. A few months before her death, she wrote to me: ‘If I were a man, I should be your enthusiastic disciple; as a woman, I can but offer you my cordial admiration’. In the same letter she explains the part which she proposed to take in diffusing the principles of the new philosophy: ‘It is always well for a woman to follow modestly behind the army of renovators, even at the risk of losing a little of her own originality’. She describes our intellectual anarchy in this charming simile: ‘We are all standing as yet with one foot in the air over the threshold of truth’. [It is for women to introduce Positivism into the Southern nations] With such a colleague, combining as she did qualities hitherto shared amongst the noblest types of womanhood, it would have been easy to induce her sex to co-operate in the regeneration of society. For she gave a perfect example of that normal reaction of Feeling upon Reason which has been here set forward as the highest aim of Woman’s efforts. When she had finished the important work on which she was engaged, I had marked out for her a definite yet spacious field of co-operation in the Positivist cause: a field which her intellect and character were fully competent to occupy. I mention it here, to illustrate the mode in which women may help to spread Positivism through the West; giving thus the first example of the social influence which they will afterwards exert permanently. What I say has special reference to Italy and to Spain. In other countries it only applies to individuals who, though living in an atmosphere of free thought, have not themselves ventured to think freely. Success in this latter case is so frequent, as to make me confident that the agencies of which I am about to speak may be applied collectively with the same favourable result.
