Know how to Appreciate. There is none who cannot teach somebody something, and there is none so excellent but he is excelled. To know how to make use of every one is useful knowledge. Wise men appreciate all men, for they see the good in each and know how hard it is to make anything good. Fools depreciate all men, not recognising the good and selecting the bad.

Meaning: Someone's belief may have been produced by what they want to be true, rather than by good evidence that it is true.

Meaning: A measure can register one property without recognising the differences that matter for another judgement. Equal weight does not mean equal value; choose evidence suited to the question.

Meaning: Making a wager is easy and does not itself demonstrate knowledge or judgement. The dismissive wording challenges treating willingness to stake something as proof of being right, rather than fairly describing the person making the bet.

Meaning: Trying every available thing without discrimination is pictured as eventually biting a poisonous weed. The warning favours judgment over indiscriminate sampling; it is a figurative caution, not evidence that curiosity is dangerous or a guide to identifying safe plants.
