it helps the ignorant and the uninformed to take a step {{U}}(38) {{/U}}
and, thereby adapt themselves to {{U}}(39) {{/U}} circumstances. But if
we make an idol of tradition, it ceases to be a guide. It becomes an obstacle
{{U}}(40) {{/U}} on the path of course. Man is to accept the help which
tradition can give but to be well aware of its limitations in a changing
world.
