In which of the texts, the following lines occur? “Of all the
causes which conspire to blind Man’s erring judgement, and
misguide the mind, What the weak head with strongest bias
rules, Is pride, the never failing vice of fools”.

The correct option is An Essay on Criticism.

Step-by-Step Explanation:
1. Identify the Lines:
The quoted lines are:
“Of all the causes which conspire to blind
Man’s erring judgement, and misguide the mind,
What the weak head with strongest bias rules,
Is pride, the never failing vice of fools”
These famous lines discuss how pride is the ultimate source of human error in judgment and critical thinking.

2. Determine the Author and Work:
These lines are written by the famous English poet Alexander Pope and are found in his celebrated poem, An Essay on Criticism, which was first published anonymously in 1711.

3. Context within the Poem:
The quote appears at the beginning of Part II of the poem. In this section, Pope discusses the various psychological and intellectual barriers to sound criticism and correct judgment. He argues that "pride" is the foremost obstacle (the "never-failing vice of fools") that prevents critics and readers from seeing the truth and appreciating art objectively. By filling the gaps of knowledge with self-importance, pride biases the mind and leads to flawed literary judgments.
