Sorrow is knowledge: they who know the most
Must mourn the deepest o’er the fatal truth,
The Tree of Knowledge is not that of Life.

Sorrow is knowledge, those that know the most must mourn the deepest, the tree of knowledge is not the tree of life.

But grief should be the instructor of the wise;
Sorrow is knowledge: they who know the most
Must mourn the deepest o’er the fatal truth,
The Tree of Knowledge is not that of Life.

True knowledge comes only through suffering

In much wisdom is much grief: and he that increaseth knowledge increaseth sorrow.

One fatal Tree there stands of Knowledge call'd, Forbidden them to taste: Knowledge forbidd'n? Suspicious, reasonless. Why should thir Lord Envie them that? can it be sin to know, Can it be death? and do they onely stand By Ignorance, is that thir happie state, The proof of thir obedience and thir faith? O fair foundation laid whereon to build Thir ruine! Hence I will excite thir minds With more desire to know, and to reject Envious commands, invented with designe To keep them low whom knowledge might exalt Equal with Gods; aspiring to be such, They taste and die: what likelier can ensue?

How dreadful the knowledge of the truth can be
When there’s no help in truth.

How dreadful knowledge of the truth can be When there's no help in truth!

There is no greater sorrow than to know another's secret when you cannot help them.

Knowledge by suffering entereth,
And life is perfected by death.

Sorrow is a king who, when he dwells in a place, does not consent to have anyone dwelled there with him.

Translation: Who gathers knowledge, also gathers woe,
And least they sorrow feel who least do know.

Since knowledge is but sorrow's spy,
It is not safe to know.

To suffer is to produce knowledge.
