Malkin, Professor of Aesthetics and Rhetoric at Tel Aviv University and the founder and academic director of Meitar College for Judaism as Culture in Jerusalem, writes: Today very many secular Jews take part in Jewish cultural activities, such as celebrating Jewish holidays as historical and nature festivals, imbued with new content and form, or marking life-cycle events such as birth, bar/bat mitzvah, marriage, and mourning in a secular fashion. They come together to study topics pertaining to Jewish culture and its relation to other cultures, in havurot, cultural associations, and secular synagogues, and they participate in public and political action coordinated by secular Jewish movements, such as the former movement to free Soviet Jews, and movements to combat pogroms, discrimination, and religious coercion. Jewish secular humanistic education inculcates universal moral values through classic Jewish and world literature and through organizations for social change that aspire to ideals of justice and charity.

Other biblical writings that associated with philosophy are Psalms that contains invitations to admire the wisdom of God through his works; from this, some scholars suggest, Judaism harbors a Philosophical under-current and Ecclesiastes that is often considered to be the only genuine philosophical work in the Hebrew Bible; its author seeks to understand the place of human beings in the world and life's meaning. Other writings related to philosophy can be found in the Deuterocanonical books such as Sirach and Book of Wisdom. During the Hellenistic era, Hellenistic Judaism aspired to combine Jewish religious tradition with elements of Greek culture and philosophy. The philosopher Philo used philosophical allegory to attempt to fuse
