The path of least resistance and least trouble is a mental rut already made. It requires troublesome work to undertake the alternation of old beliefs. Self-conceit often regards it as a sign of weakness to admit that a belief to which we have once committed ourselves is wrong. We get so identified with an idea that it is literally a pet notion and we rise to its defense and stop our eyes and ears to anything different.

The interaction of knowledge and skills with experience is key to learning.

The importance of language in gaining knowledge is doubtless the chief cause of the common notion that knowledge may be passed directly from one to another.
