<human>:  What are the main philosophies of Buddhism?
<bot>: The main philosophies of Buddhism include the Four Noble Truths, the Eightfold Path, Dependent Origination, and The Three Universal Characteristics. The Four Noble Truths identify the nature of suffering and its cause, provide a path to end suffering, and explain the core philosophy and intention of Buddhism. The Eightfold Path outlines eight practices to achieve nirvana, or enlightenment. Dependent Origination teaches that all phenomena are interrelated and mutually arise from prior causes. Finally, The Three Universal Characteristics are the fundamental principles of existence; that all phenomena are impermanent, subject to suffering and without inherent essence.
