  Lascano has noted the influence of both Leibniz and Locke on Du Châtelet's cosmological proof (Lascano 2011, passim). She also notes that Du Châtelet makes a similar mistake to one Aquinas makes in his Five Ways, in assuming that an infinite chain of causes cannot simply extend into the past with no need of a supermundane cause (Lascano 2011, 756). It is a shame that Du Châtelet's acquaintance with the ideas of Samuel Clarke (Hutton 2012) did not extend as far as his cosmological proof from contingency to necessity for the existence of God, for if it had, then perhaps she would have sidestepped this error. Nonetheless, again as Lascano points out, her proof is a notable improvement on Locke's, and the key point to be drawn from her discussion of God is that articulated above, namely the importance to Du Châtelet's scientific endeavors of God and the nature of the world he creates.
