I may set out from the old proverb that liars have bad memories. It is certain that the pathological liar has practically no memory. About male liars I shall have more to say; they are not common, however. But if we remember what was said as to the absence of memory amongst women we shall not be surprised at the existence of the numerous proverbs and common sayings about the untruthfulness of women. It is evident that a being whose memory is very slight, and who can recall only in the most imperfect fashion what it has said or done, or suffered, must lie easily if it has the gift of speech. The impulse to untruthfulness will be hard to resist if there is a practical object to be gained, and if the influence that comes from a full conscious reality of the past be not present. The impulse to lie is stronger in woman, because, unlike that of man, her memory is not continuous, whilst her life is discrete, unconnected, discontinuous, swayed by the sensations and perceptions of the moment instead of dominating them. Unlike man, her experiences float past without being referred, so to speak, to a definite, permanent centre; she does not feel herself, past and present, to be one and the same throughout all her life. It happens almost to every man that sometimes he “does not understand himself”; indeed, with very many men, it happens (leaving out of the question the facts of psychical periodicity) that if they think over their pasts in their minds they find it very difficult to refer all the events to a single conscious personality; they do not grasp how it could have been that they, being what they feel themselves at the time to be, could ever have done or felt or thought this, that, or the other. And yet in spite of the difficulty, they know that they had gone through these experiences. The feeling of identity in all circumstances of life is quite wanting in the true woman, because her memory, even if exceptionally good, is devoid of continuity. The consciousness of identity of the male, even although he may fail to understand his own past, manifests itself in the very desire to understand that past. Women, if they look back on their earlier lives, never understand themselves, and do not even wish to understand themselves, and this reveals itself in the scanty interest they give to the attempts of man to understand them. The woman does not interest herself about herself, and hence there have been no female psychologists, no psychology of women written by a woman, and she is incapable of grasping the anxious desire of the man to understand the beginning, middle, and end of his individual life in their relation to each other, and to interpret the whole as a continual, logical, necessary sequence.

At this point there is a natural transition to logic. A creature like woman, the absolute woman, who is not conscious of her own identity at different stages of her life, has no evidence of the identity of the subject-matter of thought at different times. If in her mind the two stages of a change cannot be present simultaneously by means of memory, it is impossible for her to make the comparison and note the change. A being whose memory is never sufficiently good as to make it psychologically possible to perceive identity through the lapse of time, so as to enable her, for instance, to pursue a quantity through a long mathematical reckoning; such a creature in the extreme case would be unable to control her memory for even the moment of time required to say that A will be still A in the next moment, to pronounce judgment on the identity A = A, or on the opposite proposition that A is not equal to A, for that proposition also requires a continuous memory of A to make the comparison possible.

I have been making no mere joke, no facetious sophism or paradoxical proposition. I assert that the judgment of identity depends on conceptions, never on mere perceptions and complexes of perceptions, and the conceptions, as logical conceptions, are independent of time, retaining their constancy, whether I, as a psychological entity, think them constant or not. But man never has a conception in the purely logical form, for he is a psychological being, affected by the condition of sensations; he is able only to form a general idea (a typical, connotative, representative conception) out of his individual experiences by a reciprocal effacing of the differences and strengthening of the similarities, thus, however, very closely approximating to an abstract conception, and in a most wonderful fashion using it as such. He must also be able to preserve this idea which he thinks clear, although in reality it is confused, and it is memory alone that brings about the possibility of that. Were he deprived of memory he would lose the possibility of thinking logically, for this possibility is incarnated, so to speak, only in a psychological medium.

Memory, then, is a necessary part of the logical faculty. The propositions of logic are not conditioned by the existence of memory, but only the power to use them. The proposition A = A must have a psychological relation to time, otherwise it would be At1 = At2. Of course this is not the case in pure logic, but man has no special faculty of pure logic, and must act as a psychological being.

I have already shown that the continuous memory is the vanquisher of time, and, indeed, is necessary even for the idea of time to be formed. And so the continuous memory is the psychological expression of the logical proposition of identity. The absolute woman, in whom memory is absent, cannot take the proposition of identity, or its contradictory, or the exclusion of the alternative, as axiomatic.

Besides these three conditions of logical thought, the fourth condition, the containing of the conclusion in the major premiss, is possible only through memory. That proposition is the groundwork of the syllogism. The premisses psychologically precede the conclusion, and must be retained by the thinking person whilst the minor premiss applies the law of identity or of non-identity. The grounds for the conclusion must lie in the past. And for this reason continuity which dominates the mental processes of man is bound up with causality. Every psychological application of the relation of a conclusion to its premisses implies the continuity of memory to guarantee the identity of the propositions. As woman has no continuous memory she can have no principium rationis sufficientis.

And so it appears that woman is without logic.

George Simmel has held this familiar statement to be erroneous, inasmuch as women have been known to draw conclusions with the strongest consistency. That a woman in a concrete case can unrelentingly pursue a given course at the stimulation of some object is no more a proof that she understands the syllogism, than is her habit of perpetually recurring to disproved arguments a proof that the law of identity is an axiom for her. The point at issue is whether or no they recognise the logical axioms as the criteria of the validity of their thoughts, as the directors of their process of thinking, whether they make or do not make these the rule of conduct and the principle of judgment. A woman cannot grasp that one must act from principle; as she has no continuity she does not experience the necessity for logical support of her mental processes. Hence the ease with which women assume opinions. If a woman gives vent to an opinion, or statement, and a man is so foolish as to take it seriously and to ask her for the proof of it, she regards the request as unkind and offensive, and as impugning her character. A man feels ashamed of himself, feels himself guilty if he has neglected to verify a thought, whether or no that thought has been uttered by him; he feels the obligation to keep to the logical standard which he has set up for himself. Woman resents any attempt to require from her that her thoughts should be logical. She may be regarded as “logically insane.”

The most common defect which one could discover in the conversation of a woman, if one really wished to apply to it the standard of logic (a feat that man habitually shuns, so showing his contempt for a woman’s logic) is the quaternio terminorum, that form of equivocation which is the result of an incapacity to retain definite presentations; in other words the result of a failure to grasp the law of identity. Woman is unaware of this; she does not realise the law nor make it a criterion of thought. Man feels himself bound to logic; the woman is without this feeling. It is only this feeling of guilt that guarantees man’s efforts to think logically. Probably the most profound saying of Descartes, and yet one that has been widely misunderstood, is that all errors are crimes.

The source of all error in life is failure of memory. Thus logic and ethics, both of which deal with the furtherance of truth and join in its highest service, are dependent on memory. The conception dawns on us that Plato was not so far wrong when he connected discernment with memory. Memory, it is true, is not a logical and ethical act, but it is a logical and ethical phenomenon. A man who has had a vivid and deep perception regards it as a fault, if some half-hour afterwards he is thinking of something different, even if external influences have intervened. A man thinks himself unconscientious and blameworthy if he notices that he has not thought of a particular portion of his life for a long time. Memory, moreover, is linked with morality, because it is only through memory that repentance is possible. All forgetfulness is in itself immoral. And so reverence is a moral exercise; it is a duty to forget nothing, and for this reason we should reverence the dead. Equally from logical and ethical motives, man tries to carry logic into his past, in order that past and present may become one.
