*for the degree of Bachelor of Sciences in Liberal Arts & Sciences in Computer Science + Philosophy*
---
The CS + Philosophy blended bachelor's degree is a partnership between the Department of Philosophy in the College of Liberal Arts & Sciences and the [Siebel School of Computing and Data Science in The Grainger College of Engineering](https://siebelschool.illinois.edu/academics/undergraduate/degree-program-options/cs-x-degree-programs/computer-science-philosophy). The CS + Philosophy major will prepare you to navigate and push the frontiers of computing where researchers and practitioners often face the same type of questions—from foundational to ethical—that philosophers have tackled for ages. Acquire skills in formal methods, philosophical analysis, and computer programming, all while learning from award-winning faculty invested in the relationship between computer science and philosophy.

## **Sample Sequence**
*This sample sequence is intended to be used only as a guide for degree completion. All students should work individually with their academic advisors to decide the actual course selection and sequence that works best for them based on their academic preparation and goals. Enrichment programming such as study abroad, minors, internships, and so on may impact the structure of this four-year plan. Course availability is not guaranteed during the semester indicated in the sample sequence.*
*Students must fulfill their Language Other Than English requirement by successfully completing a fourth level of a language other than English. See the corresponding section on the [Degree and General Education Requirements page](https://catalog.illinois.edu/general-information/degree-general-education-requirements/)**.*

1. Students will become familiar with traditional topics, theories, and debates in epistemology and metaphysics, in ethics and value theory, and in logic; and familiar with current developments in professional philosophy.
2. Students will gain an understanding of machine learning and the metaphysical and moral issues rising from artificial intelligence, and the various consequences for human dignity and living.
3. Students will develop the ability to analyze persuasive and argumentative prose: identifying the main claims asserted, the reasons alleged to support those claims, and the logical relations between the claims and the reasons, including identifying any gaps in the arguments.
4. In addition to formal methods, students will develop the ability to write clearly and with logical precision on a wide range of important issues, including (but not limited to): civic and social challenges at local, national, and global levels; social and cultural issues related to race, indigeneity, gender, class, sexuality, language, and disability; and the ways that complex, interdependent global systems—natural, environmental, social, cultural, economic, and political—affect and are affected by the local identities and ethical choices of individuals and institutions.
