ote ourselves to certain kinds of
investigation.

"This is what may be called to judge with discrimination, otherwise, with
common sense.

"Without this faculty, it is in vain that our memory amasses the
materials, which must serve us in the comparative examination of facts.

"And this examination can only be spoiled by decrepitude, if common sense
did not succeed in dictating its conclusions to us.

"Thanks to this faculty, we possess this accuracy of mind which permits
us to discern truth from falsehood.

"It is this power which aids us in distinguishing what we should consider

the laws of intelligence.

"Without common sense we should be like an inexperienced gardener, who,
for want of knowledge, would allow the tares to grow and would neglect
