According to Osho, a true 'man of knowledge' is a buddha—one who knows from direct experience—while a 'knowledgeable' person merely carries borrowed information and quotations. The knower is obviously beyond ignorance; the knowledgeable can be worse than the ignorant because pretension breeds hypocrisy and self-deception. Better drop secondhand certainties, remain humble about not-knowing, and seek firsthand realization through awareness.
Living the truth yourself is real knowing; pretending by quoting others is worse than honestly not knowing.
