I have always looked upon alchemy in natural philosophy to be like enthusiasm in divinity, and to have troubled the world much to the same purpose.

You are an alchemist; make gold of that.

Our present time is indeed a criticizing and critical time, hovering between the wish, and the inability to believe. Our complaints are like arrows shot up into the air at no target: and with no purpose they only fall back upon our own heads and destroy ourselves.

There is a divinity in odd numbers, either in nativity, chance or death.

[The heart] is the household divinity which, discharging its function, nourishes, cherishes, quickens the whole body, and is indeed the foundation of life, the source of all action.

The true alchemists do not change lead into gold; they change the world into words.
