Knowledge without education is but armed injustice.

Knowledge is proud that it knows so much wisdom is humble that it knows no more.

Science is the father of knowledge, but opinion breeds ignorance.

Knowledge is not eating, and we cannot expect to devour and possess what we mean. Knowledge is recognition of something absent it is a salutation, not an embrace.

When you deal with a person who's experiencing dementia, you can see where they're struggling with knowledge. You can see what they forget completely, what they forget but they know what they once knew. You can tell how they're trying to remember.
