συλλήβδην, ‘in short,’ an adv. formed from the stem of the verb συλλαμβάνειν; cp. κρύβδην from κρύπτειν and σποράδην from σπείρειν.
δυνάμεως: here ‘capacity’, ‘faculty’. δύναμις from meaning ‘power’ comes to mean ‘the power to produce a certain effect’, so ‘capacity’. In Aristotle by a further refinement of meaning δύναμις is a ‘capability’, a ‘potentiality’, or power which has virtual existence but is not actually brought into play, as opposed to ἐνέργεια, a capability which is put into action.
ἀλόγως = ἄνευ λόγου, ‘without the assistance of speech.’
τοὺς εἰς τὰ τῶν θεῶν ἐξαμαρτάνοντας: i.e. those who rob or profane the property of the gods.
