“We associate truth with convenience, with what most closely accords with self-interest and personal well-being or promises to best avoid awkward effort or unwelcome dislocation of life.

We also find highly acceptable what contributes most to self esteem.

[Economic and social behaviour] are complex, and to comprehend their character is mentally tiring. Therefore we adhere, as though to a raft, to those ideas which represent our understanding.”
