Our philosophy… reduceth to a single origin and relateth to a single end, and maketh contraries to coincide so that there is one primal foundation both of origin and of end. From this coincidence of contraries, we deduce that ultimately it is divinely true that contraries are within contraries; wherefore it is not difficult to compass the knowledge that each thing is within every other.

As translated by Dorothea Waley Singer (1950) - De immenso (1591)
