A little knowledge is a dangerous thing

अज्ञः सुखमाराध्यः सुखतरमाराध्यते विशेषज्ञः ।
ज्ञानलवदुर्विदग्धं ब्रह्मापि नरं न रञ्जयति ॥

- नीतिशतकम्

- हितोपदेशः

An ignorant man can be pleased easily. A wise man can be persuaded even more easily. But even the creator cannot win over a conceited snob smattering with his little knowledge.

A little knowledge is a dangerous thing. So is a lot!
