Behold scripture says: "Hen fear of G-d - this is wisdom" (Job 28:28). Our Sages of blessed memory commented (Shab 31b), "'Hen' [hints to] 'one', for in Greek 'one' is designated as 'Hen'". Behold, that fear of G-d is considered wisdom - and this alone is [true] wisdom. And certainly that which does not require investigation cannot be called "wisdom".
