My contribution aims to discuss an apparent paradox of Theological-Political Treatise concerning the real nature of Moses’ Revelation. Moses heard a real voice or he just imagined it? Apparently, Spinoza supports both hypotheses. In this essay a try to explain this apparent paradoxical issue of Spinoza conception of religion, according a central role to the notion of wonder. In order to do this, try to show how Ethics’ conception of wonder allows to distinguish two different uses of this notion in TTP. One directly connected with Moses’ revelation, the other with superstition.
