I am currently working my way through wheelock's (chapter 36) and I feel fairly confident in what I've learned so far. However on the side just for fun I like to write my on little stories trying to use what I've learned. I've come across a question about the word 'should' while I'm making up sentences. For example "a man should be wise". I've considered two ways of writing this in latin one is the use of 'debere' as in "vir debet sapere" or something like that but it seems like that would be translated "a man ought to be wise". The second way I've considered is with the jussive subjunctive which although most commonly translated with "let" wheelock says 'should' can also be used as in 'vir debeat sapere'. So my question is, is either of these correct or both or neither?
Thank you for all your help,
