Having read "...is an ethical duty to acquire knowledge in order to improve our understanding", my person thought to investigate the matter in frame of the Dhamma. Against this sentence stands the common public idea and advertising of "knowledge, info, is a common right".
What does the Buddha say, right view accounts, in relation whether understanding is a "bring-duty, debt" (Bringschuld, [Jura] debt to be discharged at creditor's domicile, duty to inform the colleagues) or a "gain duty, debt" (Holschuld, [JURA] debt to be discharged at the domicile of the debtor /obligation to be performed at the place of business of the debtor)?
Does one with right view think "I have/would have a right for knowledge and understanding" or "I have/would have to make sacrifices to gain knowledge and understanding?
Of course one can use google to help investigating.
