Translations for trend in French

Here are paragraphs from public domain books translated:

"Well, of course, I am aware that there is not any what you might call definite evidence. I alluded merely to the trend of modern thought and the general scientific point of view, if I might so express it."	— Oui, bien entendu, il n’en est pas un qui constitue, au sens du mot, une preuve. Je faisais simplement allusion à ce que j’appellerai la tendance scientifique générale, de la pensée moderne.
