This contribution aims at putting forth two different receptions of the Aristotelian conception of the intellectual contemplation as the unique source of human happiness. As it is defined in the Nicomachean Ethics, Aristotle understands intellectual contemplation as a philosophical activity, based on the same model as the divine activity of the prime mover. Following Aristotle, Avicenna defines beatitude in pure philosophical terms, thus excluding any religious requisite or divine intervention. Albert the Great appears to be extremely dependent from Aristotle’s and (...) Avicenna’s influences but includes theological contemplation based on the lux gloriae for human beatitude. Beyond the historical interest, this paper hopes to provide an insight into the relationship between terrestrial happiness and celestial beatitude and to show how philosophy and theology interact to construe such a relation.
