We can, following the exemple of Kant, consider the moral development and improvement of men, as the supreme goal of human evolution.

The moral improvement demands an evolution leading to a higher consciousness.

The precept to worship God 'in spirit and in truth' recommand to worship him as an inward and moral force, without physical attributes and with no relation to fears and egoist wishes.

There is a radical dualism between the empirical nature of man and its moral nature.

If the present civilisation does not acquire some stable moral fondations ("bases morales stables", Fr.), its existence will hardly be more assured than that of the civilisations that have preceeded it, and which have fallen (or collapse, or failed).
