Spinoza sought in his lifetime neither riches, nor sensual pleasure, nor fame. He wrote and published his books when he could and thought advisable because part of his joy consisted in extending, as he said, a helping hand to others, in bringing them to see and understand things as he did. If they did not see, or obdurately refused to understand, he did not consider it part of his task to overcome them. He was animated by no missionary zeal. He was content to search for the truth and to explain what he found as best he could. The truth, he devoutly believed, would make us free. But it was truth that we understood, not truth that was forced upon us. He was quite satisfied to leave in his desk the manuscript of his _Ethics_. People in his lifetime did not want to listen to him. If ever they did after his death, they were cordially welcome to. In death as in life they would find him faithful to his ideal. Spinoza has often been likened to the old Hebrew prophets. He does not, it is true, exhort the people to follow in the path of righteousness; it is the philosopher's task simply to show the way. But the morality Spinoza stands for is the old prophetic morality purified and made consistent with itself. And Spinoza was, in his own time, as the prophets were in theirs, a heretic and a rebel, a voice calling in the wilderness--a wilderness that was later to become the very citadel of civilization. Excommunicated by the Jews and vilified by the Gentiles during his lifetime, Spinoza has, since his death, been canonized by both alike as the most saintly and exalted of philosophers. Like his forerunners of old, Spinoza was a prophet _in_ Israel, _for_ Mankind. INTRODUCTION TO THE PHILOSOPHY OF SPINOZA I Spinoza's philosophy has suffered not a little from the highly abstruse and technical form in which the _Ethics_ is written. Some, who are not inured to the hardships of philosophy, quite naturally jump to the conclusion that its formidable geometry contains only the most inscrutable of philosophic mysteries; and a wise humility persuades them to forego the unexampled enlightenment a mastery of the difficulties would yield. Others, who are devoutly wedded to what they consider the unreservedly empirical character of modern (that is, true) philosophy, avoid the _Ethics_ because they are convinced, on general principles, that only a mind hopelessly lost in the dark night of medieval speculation could conceive of philosophy in such ultra-deductive fashion. Reason was for so long servile to idle theology, it is not at all surprising that a work exemplifying reason to such high degree as does the _Ethics_, should receive scant respect from intrepid empiricists. It is so easy to confuse the rationalizations of reason with the nature of reason itself.
