…the synechist will not admit that physical and psychical phenomena are entirely distinct, – whether as belonging to different categories of substance, or as entirely separate sides of one shield, – but will insist that all phenomena are of one character, though some are more mental and spontaneous, others more material and regular. Still, all alike present that mixture of freedom and constraint, which allows them to be, nay, makes them to be teleological, or purposive.
