Love works in a circle, for the beloved moves the lover by stamping a likeness, and the lover then goes out to hold the beloved inreality. Who first was the beginning now becomes the end of motion.
Thomas AquinasIf there were some solitary or feral man, the passions of the soul would be sufficient for him; by them he would be conformed to things in order that he might have knowledge of them. But because man is naturally political and social, there is need for one man to make his conceptions known to others, which is done with speech. So significant speech was needed if men were to live together. Which is why those of different tongues do not easily live together.
Thomas Aquinas
