his task would never end. He would exhaust his strength in preparatory exercises, without advancing beyond them. As, from the shortness of his life, he has not the time, nor, from the limits of his intelligence, the capacity, to accomplish this, he is reduced to take upon trust a number of facts and opinions which he has not had either the time or the power to verify himself, but which men of greater ability have sought out, or which the world adopts. On this groundwork he raises for himself the structure of his own thoughts; nor is he led to proceed in this manner by choice, so much as he is constrained by the inflexible law of his condition.
There is no philosopher of such great parts in the world, but that he believes a million of things on the faith of other people, and supposes a great many more truths than he demonstrates.
This is not only necessary but desirable. A man who should undertake to inquire into everything for himself, could devote to each thing but little time and attention. His task would keep his mind in perpetual unrest, which would prevent him from penetrating to the depth of any truth, or of grappling his mind indissolubly to any conviction. His intellect would be at once independent and powerless. He must therefore make his choice from amongst the various objects of human belief, and he must adopt many opinions without discussion, in order to search the better into that smaller number which he sets apart for investigation. It is true, that whoever receives an opinion on the word of another, does so far enslave his mind; but it is a salutary servitude which allows him to make a good use of freedom.
A principle of authority must then always occur, under all circumstances, in some part or other of the moral and intellectual world. Its place is variable, but a place it necessarily has. The independence of individual minds maybe greater, or it may be less: unbounded it cannot be.
