But there is also a wider sense of “free thought,” which I regard as of still greater importance. Indeed, the harm done by traditional religions seems chiefly traceable to the fact that they have prevented free thought in this wider sense. The wider sense is not so easy to define as the narrower, and it will be well to spend some little time in trying to arrive at its essence. When we speak of anything as “free,” our meaning is not definite unless we can say what it is free _from_. Whatever or whoever is “free” is not subject to some external compulsion, and to be precise we ought to say what this kind of compulsion is. Thus thought is “free” when it is free from certain kinds of outward control which are often present. Some of these kinds of control which must be absent if thought is to be “free” are obvious, but others are more subtle and elusive. To begin with the most obvious. Thought is not “free” when legal penalties are incurred by the holding or not holding of certain opinions, or by giving expression to one’s belief or lack of belief on certain matters. Very few countries in the world have as yet even this elementary kind of freedom. In England, under the Blasphemy Laws, it is illegal to express disbelief in the Christian religion, though in practice the law is not set in motion against the well-to-do. It is also illegal to teach what Christ taught on the subject of non-resistance. Therefore, whoever wishes to avoid becoming a criminal must profess to agree with Christ’s teaching, but must avoid saying what that teaching was. In America no one can enter the country without first solemnly declaring that he disbelieves in anarchism and polygamy; and, once inside, he must also disbelieve in communism. In Japan it is illegal to express disbelief in the divinity of the Mikado. It will thus be seen that a voyage round the world is a perilous adventure. A Mohammedan, a Tolstoyan, a Bolshevik, or a Christian cannot undertake it without at some point becoming a criminal, or holding his tongue about what he considers important truths. This, of course, applies only to steerage passengers; saloon passengers are allowed to believe whatever they please, provided they avoid offensive obtrusiveness. It is clear that the most elementary condition, if thought is to be free, is the absence of legal penalties for the expression of opinions. No great country has yet reached to this level, although most of them think they have. The opinions which are still persecuted strike the majority as so monstrous and immoral that the general principle of toleration cannot be held to apply to them. But this is exactly the same view as that which made possible the tortures of the Inquisition. There was a time when Protestantism seemed as wicked as Bolshevism seems now. Please do not infer from this remark that I am either a Protestant or a Bolshevik.
