214 OF THE ADVANCEMENT OF LEARNING 



sions which intervene, and are many times more proper 

 and propitious for somewhat that he shall need after 

 wards, than for that which he urgeth for the present ; 

 and therefore men must be perfect in that rule, Haeo 

 oportet facere, et ilia non omittere. 



41. Another precept of this knowledge is, not to 

 engage a man s self peremptorily in any thing, though 

 it seem not liable to accident ; but ever to have a win
