 132 OUR UNCONSCIOUS PHILOSOPHIZING

Philosophy, then, can afford to accept the unfavorable opinion of common sense, and may even boast of it. Philosophy is unpractical, too general, and intangible. If the condemnation implied in these terms were decisive and final, then philosophy would be compelled to give up. But philosophy is not merely contrary to common sense, for it emancipates the mind from common sense and establishes the more authoritative standards by which it is itself justified.

Though I should have persuaded you that philosophy is a strange thing which you must visit abroad in its own home, nevertheless I now hope to persuade you that you once entertained it unawares. Though, if philosophy is now to enter, you must expel from your mind the ideas that make themselves most at home there, this same philosophy was once a favorite inmate. Only you were too young, and your elders had too much common sense, to know that it was philosophy. Unless you were an extraordinary child you were very curious about what you called the world; curious as to who or what made it, why it was made, how it was made, why it was made as it is, and what it is like in those remote and dim regions beyond the range of your senses. Then you grew up, and having grown up, you acquired common sense, or rather common sense acquired you. It descended like a curtain, shutting out the twilight, and enabling you to see more clearly, but just as certainly making your view more circumscribed. Since then you have come to feel that the questions of your childhood were foolish questions, or extravagant questions that no busy man can afford to indulge in.

And when one recovers this first untrammeled curiosity about things, common sense appears not as the illumination of mature years, but rather as a hardening of the mind, the worldliness and complacency of a life immersed in affairs. It would not be unfair to say that the philosophical interest is the more liberal, common sense having about it something of the quality of professionalism. But there is another and a more important sense in which
