Or the contest may be for intellectual liberty--for free thought and free speech. It is sometimes considered that such liberty meets its strongest opponent in the religious or ecclesiastical organization. There is no doubt a conservative tendency in religion. As we have pointed out, religion is the great conservator of group values and group standards. Its ritual is most elaborate, its taboos most sacred. Intellectual criticism tends to undermine what is outgrown or merely habitual here as elsewhere. Rationalism or free thought has set itself in frequent opposition likewise to what has been claimed to be "above reason." Nevertheless it would be absurd to attribute all the individualism to science and all the conservatism to religion. Scientific dogmas and "idols" are hard to displace. Schools are about as conservative as churches. And on the other hand the struggle for religious liberty has usually been carried on not by the irreligious but by the religious. The prophet Amos found himself opposed by the religious organization of his day when he urged social righteousness, and the history of the noble army of martyrs is a record of appeal to individual conscience, or to an immediate personal relation to God, as over against the formal, the traditional, the organized religious customs and doctrines of their age. The struggle for religious toleration and religious liberty takes its place side by side with the struggles for intellectual and political liberty in the chapters of individualism.
