Dialogue of Justin Martyr with Trypho

<p>Does philosophy then make happiness? said he interrupting. </p><p><br></p><p>Assuredly' I said 'and it alone.' </p><p><br></p><p>'What then is philosophy?' he says; 'and what is happiness? Pray tell me unless something hinders you from saying.'</p><p><br></p><p>'Philosophy then' said I 'is the knowledge of that which really exists and a clear perception of the truth; and happiness is the reward of such knowledge and wisdom.'</p><p><br></p><p>'But what do you call God?' said he. </p><p><br></p><p>'That which always maintains the same nature and in the same manner and is the cause of all other things -that indeed is God.'</p>
