Opinion is of two kinds: common opinion, which springs up among grave and discreet men and has the appearance of truth; and opinion which springs up among light and foolish men, without the semblance of truth.

Explanation

Not all opinion carries equal weight — the law distinguishes between the considered judgment of the learned and the idle talk of the uninformed.

Where this applies

• Not all opinions carry equal weight — expert opinion differs from casual gossip.
• The considered judgment of knowledgeable people is worth more than uninformed chatter.
• The law distinguishes between the opinion of the wise and the talk of the ignorant.
