Sensation as the Origin of Belief and Reason

Notes

1. §13.1τὴν αἴσθησιν ἀρχὴν εἶναι πίστεώς — An accusative-with-infinitive (A.C.I.) construction governed by the verb φησιν. Here, τὴν αἴσθησιν is the subject accusative of the infinitive εἶναι, ἀρχὴν is the predicate accusative, and πίστεώς is an objective genitive dependent on ἀρχὴν, meaning "the beginning of belief."
2. §13.1πρὸς τὸ λόγον — The text presents the neuter article τὸ, which does not agree in gender with the masculine accusative noun λόγον. This is highly likely a typographical error or variant reading for τὸν λόγον. The translation proceeds on the assumption of τὸν λόγον ("to the reason").
