The past is pregnant with the present.

The greatness of a life can only be estimated by the multitude of its actions. We should not count the years, it is our actions which constitute our life.

I have said more than once, that I hold space to be something purely relative, as time; an order of coexistences, as time is an order of successions.

I hold that it is only when we can prove everything we assert that we understand perfectly the thing under consideration.

There is a world of created beings - living things, animals, entelechies, and souls - in the least part of matter.... Thus there is nothing waste, nothing sterile, nothing dead in the universe; no chaos, no confusions, save in appearance.

Natural religion itself, seems to decay very much. Many will have human souls to be material: others make God himself a corporeal being.

I do not conceive of any reality at all as without genuine unity.
