Their languages are totally unlike.

These same similarities present themselves over such wide areas and between nations so remote and of such different culture, that the theory of a parallelism of development is after all the more credible explanation.
The impressions which natural occurrences make on minds of equal stages of culture are very much alike.

The same thoughts are evoked, and the same expressions suggest themselves as appropriate to convey these thoughts in spoken language.

This is often exhibited in the identity of expression between master-poets of the same generation, and between cotemporaneous thinkers in all branches of knowledge.

Still more likely is it to occur in primitive and uncultivated conditions, where the most obvious forms of expression are at once adopted, and the resources of the mind are necessarily limited.
