773. Not any knowledge is hurtful or detrimental, provided it is not considered to be everything in itself, but a further goal is looked to. It is spiritual wealth, on which the understanding of realities can be based. It is just the same as with riches or wealth, and with power: if one values them only for the sake of riches and power, then one is very badly off in the other life, whereas if they are valued only for further ends, so that they are only means, and are thus regarded as nothing apart from the end, then they do no one any harm. 1748, 14 February.
