President Kennedy will speak at Boston College Saturday. At the ceremonies, culminating a week-long observance of the college's centennial celebration, President Pusey will receive an honorary degree.

Bunn, President of Georgetown University, and Lady Barbara Ward Jackson, British economist and author, will also be honored.

During this week's celebration, prominent theologians and scholars have been participating in a series of discussions and lectures relating the roles of the church and tradition. Sessions today, tomorrow, and Friday will deal with a colloquy on the humanities, the social sciences, and the natural sciences. The theme of the three-day colloquium is "The Knowledge Explosion: Liberation and Limitation."
