Once when such a sudden halt occurred on the line outside a station, a young lady who was in the carriage said that perhaps there was going to be a collision, and that the best thing to do was to raise the legs high. This phrase “raise the legs” had associations with many walks and excursions into the country, which he had shared with the girl mentioned above in the happy early days of their love. Here was a new argument for the contention that he would be mad to marry her now; nevertheless, my knowledge of the situation led me to regard it as certain that there existed in him all the same the desire to fall a victim to this form of madness. THIRTEENTH LECTURE ARCHAIC AND INFANTILE FEATURES IN DREAMS Let us start afresh from our conclusion that, under the influence of the censorship, the dream-work translates the latent dream-thoughts into another form. These thoughts are of the same nature as the familiar, conscious thoughts of waking life; the new form in which they are expressed is, owing to many peculiar characteristics, incomprehensible to us. We have said that it goes back to phases in our intellectual development which we have long outgrown—to hieroglyphic writing, to symbolic-connections, possibly to conditions which existed before the language of thought was evolved. On this account we called the form of expression employed by the dream-work _archaic_ or _regressive_. From this you may draw the inference that a more profound study of the dream-work must lead to valuable conclusions about the initial stages of our intellectual development, of which at present little is known. I hope it will be so, but so far this task has not been attempted. The era to which the dream-work takes us back is “primitive” in a twofold sense: in the first place, it means the early days of the _individual_—his childhood—and, secondly, in so far as each individual repeats in some abbreviated fashion during childhood the whole course of the development of the human race, the reference is _phylogenetic_. I believe it not impossible that we may be able to discriminate between that part of the latent mental processes which belongs to the early days of the individual and that which has its roots in the infancy of the race. It seems to me, for instance, that symbolism, a mode of expression which has never been individually acquired, may claim to be regarded as a racial heritage.
