one may as well not know a thing at all as know it imperfect

Someone may as well do thing1 as do thing2.
这句话的意思是他本来要做thing2,但是他发现做thing1也一样容易或更容易,所以他就做了thing1.那么这句话直译的意思是：
For someone,to do thing1 is the same as to do thing2
所以,两件事本来是等同的.但是因为他先要做thing2而没做,所以实际的意思thing1比thing2有优先性.
翻译:
与其一知半解,不如一无所知.
